See commit b6a2fea39318e43fee84fa7b0b90d68bed92d2ba ("mm: variable length argument support") for details. However, if you have a small stack limit (perhaps because you need lots of stacks in a threaded environment), the new heuristic of allowing up to 1/4th of RLIMIT_STACK to be used for argument and environment strings could actually be smaller than the old limit. So just say that it's ok to have up to ARG_MAX strings regardless of the value of RLIMIT_STACK, and check the rlimit only when going over that traditional limit. (Of course, if you actually have a *really* small stack limit, the whole stack itself will be limited before you hit ARG_MAX, but that has always been true and is clearly the right behaviour anyway).

The PTEs for each segment start on a 4K boundary, so with 16M pages we have 16 PTEs per segment and then a gap to the next 4K page boundary. It might be possible to allocate the PTEs for each segment separately, saving the memory currently filling the gaps. However we'd need to check that's OK with the hardware, and that it actually saves memory.

However it doesn't cater for the IOMMU window starting at a non-zero address, as the base of the window is not incorporated into pte_offset at all.

This is because auditd stops, then the script deletes all of the rules. These deletions are sent as audit messages out of the printk kernel interface which is already known to be lossy. These will overun the default kernel rate limiting (10 really fast messages) and will call audit_panic(). The same effect can happen if a slew of avc's come through while auditd is stopped. This can be fixed a number of ways but this patch fixes the problem by just not panicing if auditd is not running. We know printk is lossy and if the user chooses to set the failure mode to panic and tries to use printk we can't make any promises no matter how hard we try, so why try? At least in this way we continue to get lost message accounting and will eventually know that things went bad. The other change is to add a new call to audit_log_lost() if auditd disappears. We already pulled the skb off the queue and couldn't send it so that message is lost. At least this way we will account for the last message and panic if the machine is configured to panic. This code path should only be run if auditd dies for unforeseen reasons. If auditd closes correctly audit_pid will get set to 0 and we won't walk this code path.

As it turns out, calling ARM's get_unaligned() on a u64 pointer pointing to the following byte sequence: 80 81 82 83 84 85 86 87 would return ffffffff83828180 (LE mode.) This turns out to be because of implicit u8 -> int promotion in ARM's implementation of various helpers for get_unaligned(), causing them to accidentally return signed instead of unsigned values, which in turn caused the subsequent casts to unsigned long long in __get_unaligned_8_[bl]e() to sign-extend the lower words. Fix by casting the return values of __get_unaligned_[24]_[bl]e() to unsigned int.

This per-CPU access needs to be done in such a way as to guarantee that the code using it cannot move to some other CPU before all uses of the value accessed have completed. Even though this code is currently only invoked from softirq context, which currrently cannot migrate to some other CPU, life would be better if this code did not silently make such an assumption.

If a program using huge pages does not explicitly unmap them, they remain mapped (and therefore, are lost) after the program exits. I observed that the free huge page count in /proc/meminfo decreased when running my program, and it did not increase after the program exited. After running the program a few times, no more huge pages could be allocated. The reason for this seems to be that the x86 pmd_bad and pud_bad consider pmd/pud entries having the PSE bit set invalid. I think there is nothing wrong with this bit being set, it just indicates that the lowest level of translation has been reached. This bit has to be (and is) checked after the basic validity of the entry has been checked, like in this fragment from follow_page() in mm/memory.c: if (pmd_none(*pmd) || unlikely(pmd_bad(*pmd))) goto no_page_table; if (pmd_huge(*pmd)) { BUG_ON(flags & FOLL_GET); page = follow_huge_pmd(mm, address, pmd, flags & FOLL_WRITE); goto out; } Note that this code currently doesn't work as intended if the pmd refers to a huge page, the pmd_huge() check can not be reached if the page is huge. Extending pmd_bad() (and, for future 1GB page support, pud_bad()) to allow for the PSE bit being set fixes this. For similar reasons, allowing the NX bit being set is necessary, too. I have seen huge pages having the NX bit set in their pmd entry, which would cause the same problem.

This regression was introduced in 970451. With no mount options specified, xfs_parseargs() does the following: int ikeep = 0; args->flags |= XFSMNT_BARRIER; args->flags2 |= XFSMNT2_COMPAT_IOSIZE; if (!options) goto done; It only sets the above two options by default and before, it also used to set XFSMNT_IDELETE by default. If options are specified, then if (!(args->flags & XFSMNT_DMAPI) && !ikeep) args->flags |= XFSMNT_IDELETE; is executed later on which is skipped by the "goto done;" above. The solution is to invert the logic.

The problem is that the 'valid' bit is stored in the ESID, which is always written after the VSID. Overwriting the VSID first will make the original ESID entry point to the new VSID, which means that any concurrent DMA accessing the old ESID ends up being redirected to the new virtual address. A few cycles later, we write the new ESID and everything is fine again. That race can be closed by writing a zero entry to the ESID first, which makes sure that the VSID is not accessed until we write the new ESID. Note that we don't actually need to invalidate the SLB entry using the invalidation register, which would also flush any ERAT entries for that segment, because the segment translation does not become invalid but is only removed from the SLB cache.

This patch cleans that up, and makes the protocol and address family registration names in SCTP more regular, increasing readability.

Otherwise, the TIF_DEBUG flag must be unset. Currently, the child inherits TIF_DEBUG from the parent before copy_thread is called, so TIF_DEBUG may be already be set before we determine whether the child is supposed to inherit debugging capabilities from the parent or not. This means that ocd_enable() won't increment the refcount, because TIF_DEBUG is already set, and that TIF_DEBUG will be set for processes that aren't being debugged. This leads to a refcounting asymmetry, which may show up as ------------[ cut here ]------------ Badness at arch/avr32/kernel/ocd.c:73 PC is at ocd_disable+0x34/0x60 LR is at put_lock_stats+0xa/0x20 as reported by David Brownell.

Four tunnel drivers (ip_gre, ipip, ip6_tunnel and sit) can receive a pre-defined name for a device from the userspace. Since these drivers call the register_netdevice() (rtnl_lock, is held), which does _not_ generate the device's name, this name may contain a '%' character. Not sure how bad is this to have a device with a '%' in its name, but all the other places either use the register_netdev(), which call the dev_alloc_name(), or explicitly call the dev_alloc_name() before registering, i.e. do not allow for such names.

After we up_read() the mmap_sem, it's possible that the context is destroyed by its owning thread, and so the later references to ctx are invalid. This can maifest as a deadlock on the (now free()-ed) context state mutex. This change adds a reference to the context before we release the mmap_sem, so that the context cannot be destroyed.

Deleting the address and adding a new is a less intrusive workaround. But I still beleive this is a bug that should be fixed. Some way or another. Another possibility would be to remove the scope mangling based on address. This will always be incomplete (are 127/8 the only address space with host scope requirements?) We set the scope to RT_SCOPE_HOST if an IPv4 interface is configured with a loopback address (127/8). The scope is never reset, and will remain set to RT_SCOPE_HOST after changing the address. This patch resets the scope if the address is changed again, to restore normal functionality. Signed-off-by: Bjorn Mork Signed-off-by: David S.

(The first two lines are printout loops from -git7 forward-ported to -git8, the third line is the same printout loop added just after the xor-with-cleared_cpu_caps[] loop.) Here's how the breakage occurs: 1. arch/x86/kernel/tsc_32.c:tsc_init() sees !cpu_has_tsc, so bails and calls setup_clear_cpu_cap(X86_FEATURE_TSC). 2. include/asm-x86/cpufeature.h:setup_clear_cpu_cap(bit) clears the bit in boot_cpu_data and sets it in cleared_cpu_caps 3. arch/x86/kernel/cpu/common.c:identify_cpu() XORs all caps in with cleared_cpu_caps HOWEVER, at this point c->x86_capability correctly has TSC Off, cleared_cpu_caps has TSC On, so the XOR incorrectly sets TSC to On in c->x86_capability, with disastrous results. The real bug is that clearing bits with XOR only works if the bits are known to be 1 prior to the XOR, and that's not true here. A simple fix is to convert the XOR to AND-NOT instead. The following patch does that, and allows my 486 to boot 2.6.25-rc kernels again. [ mingo@elte.hu: fixed a similar bug in setup_64.c as well. ] The breakage was introduced via commit 7d851c8d3db0.

The only safe thing for now is to remove the patching. This code was broken since v2.6.21.

That name led me on the wrong path with the KERNEL_TEXT_SIZE regression, because i knew how big of _text_ my images have and i knew about the 40 MB "text" limit so i wrongly thought to be on the safe side of the 40 MB limit with my 29 MB of text, while the total image size was slightly above 40 MB.

(should anyone be that crazy or lazy) We have a full 4K of pagetable (level2_kernel_pgt) allocated for these mappings already, so there's no RAM overhead and the limit was rather pointless and arbitrary.

Peter Anvin Date: Wed Feb 13 11:16:46 2008 -0800 x86: handle BIOSes which terminate e820 with CF=1 and no SMAP The proper way to terminate the e820 chain is with %ebx == 0 on the last legitimate memory block. However, several BIOSes don't do that and instead return error (CF = 1) when trying to read off the end of the list. For this error return, %eax doesn't necessarily return the SMAP signature -- correctly so, since %ah should contain an error code in this case. To deal with some particularly broken BIOSes, we clear the entire e820 chain if the SMAP signature is missing in the middle, indicating a plain insane e820 implementation. However, we need to make the test for CF = 1 before the SMAP check. This fixes at least one HP laptop (nc6400) for which none of the memory-probing methods (e820, e801, 88) functioned fully according to spec. Signed-off-by: H.

Oops is at [1]. Bisection led to the following commit: commit 37cc8d7f963ba2deec29c9b68716944516a3244f x86/early_ioremap: don't assume we're using swapper_pg_dir At the early stages of boot, before the kernel pagetable has been fully initialized, a Xen kernel will still be running off the Xen-provided pagetables rather than swapper_pg_dir[]. Therefore, readback cr3 to determine the base of the pagetable rather than assuming swapper_pg_dir[]. static inline pmd_t * __init early_ioremap_pmd(unsigned long addr) { - pgd_t *pgd = &swapper_pg_dir[pgd_index(addr)]; + /* Don't assume we're using swapper_pg_dir at this point */ + pgd_t *base = __va(read_cr3()); + pgd_t *pgd = &base[pgd_index(addr)]; pud_t *pud = pud_offset(pgd, addr); pmd_t *pmd = pmd_offset(pud, addr); Trying to analyze the problem, it seems on the guest side of lguest, %cr3 has a different value from &swapper_pg-dir (which is AFAIK fine on a pravirt guest): Putting some debugging messages in early_ioremap_pmd: /* Appears 3 times */ [ 0.000000] *************************** [ 0.000000] __va(%cr3) = c0000000, &swapper_pg_dir = c02cc000 [ 0.000000] *************************** After 8 hours of debugging and staring on lguest code, I noticed something strange in paravirt_ops->set_pmd hypercall invocation: static void lguest_set_pmd(pmd_t *pmdp, pmd_t pmdval) { *pmdp = pmdval; lazy_hcall(LHCALL_SET_PMD, __pa(pmdp)&PAGE_MASK, (__pa(pmdp)&(PAGE_SIZE-1))/4, 0); } The first hcall parameter is global pgdir which looks fine. The second parameter is the pmd index in the pgdir which is suspectful. AFAIK, calculating the index of pmd does not need a divisoin over four. Removing the division made lguest work fine again . Patch is at [2]. I am not sure why the division over four existed in the first place. It seems bogus, maybe the Xen patch just made the problem appear ? [2]: The patch: [PATCH] lguest: fix pgdir pmd index cacluation Remove an error in index calculation which leads to removing a not existing shadow page table (leading to a Null dereference).

The crash handler fn is triggered by the recently introduced PPC crash shutdown reg/unreg functions.

When writing to a file, ext4_get_block_wrap() is called with create=1 in order to request that blocks be allocated if necessary. It currently calls ext4_get_blocks() with create=0 in order to do a lookup first. If the inode contains an unitialized data block, the buffer head is left unampped, which ext4_get_blocks_wrap() returns, causing the BUG. We fix this by checking to see if the buffer head is unmapped, and if so, we make sure the the buffer head is mapped by calling ext4_ext_get_blocks with create=1.

They are all immediately completed with host busy status, and application clients or filesystems will break quickly. The SCSI device might even be taken offline: http://bugzilla.kernel.org/show_bug.cgi?id=9734 The only remedy seems to be to block the SCSI device until reconnect. Alas the SCSI core has no useful API to block only one logical unit i.e. the scsi_device, therefore we block the entire Scsi_Host. This currently corresponds to an SBP-2 target. In case of targets with multiple logical units, we need to satisfy the dependencies between logical units by carefully tracking the blocking state of the target and its units. We block all logical units of a target as soon as one of them needs to be blocked, and keep them blocked until all of them are ready to be unblocked. Furthermore, as the history of the old sbp2 driver has shown, the scsi_block_requests() API is a minefield with high potential of deadlocks. We therefore take extra measures to keep logical units unblocked during __scsi_add_device() and during shutdown. This avoids I/O errors during reconnect in many but alas not in all cases. There may still be errors after a re-login had to be performed. Also, some bridges have been seen to cease fetching management ORBs if I/O went on up until a bus reset. In these cases, all management ORBs time out after mgt_orb_timeout. The old sbp2 driver is less vulnerable or maybe not vulnerable to this, for as yet unknown reasons.

This should be fixed eventually. An actual failure of __scsi_add_device is easy to handle, but an incomplete execution of __scsi_add_device with an sdev returned would remain undetected and leave the SBP-2 target unusable. Therefore we use a workaround: If there was a bus reset during __scsi_add_device (i.e. during the SCSI probe), we remove the new sdev immediately, log out, and attempt login and SCSI probe again.

In this case, log out before attempting the reconnect. Else several firmwares will deny the re-login because they somehow didn't invalidate the old login. Also, don't retry reconnects in this situation. The retries won't succeed either. These changes improve chances for successful re-login and shorten the period during which the logical unit is inaccessible.

In those cases, __scsi_add_device succeeded and returned the pointer to the existing scsi_device. fw-sbp2 then continued orderly, except that it missed to call sbp2_cancel_orbs. SCSI core would call fw-sbp2's eh_abort_handler eventually if there had been an outstanding command. This patch avoids the needless lookups and temporary allocations in SCSI core and I/O stall and timeout until eh_abort_handler hits. Also, __scsi_add_device tolerating calls for devices which already exist is undocumented behavior on which we shouldn't rely.

They are therefore unable to respond to SCSI INQUIRY immediately, and the SCSI core has to retry the INQUIRY. One of these retries is typically successful, and all is well. But in case of Momobay FX-3A, the INQUIRY retries tend to fail entirely. This can usually be avoided by waiting a little while after login before letting the SCSI core send the INQUIRY. The old sbp2 driver handles this more gracefully for as yet unknown reasons (perhaps because it waits for fetch agent resets to complete, unlike fw-sbp2 which quickly proceeds after requesting the agent reset). Therefore the workaround is not as much necessary for sbp2.

The fix is obvious: Free the minor number *after* instead of *before* device_unregister(). This requires to take an additional reference of the fw_device as long as the IDR tree points to it. And while we are at it, we fix an additional race condition: fw_device_op_open() took its reference of the fw_device a little bit too late, hence was in danger to access an already invalid fw_device.

If the SCSI INQUIRY failed and hence __scsi_add_device failed due to a bus reset, we tried a logout and then waited for the already scheduled login work to happen. So far so good, but the generation used for the logout was outdated, hence the logout never reached the target. The target might therefore deny the subsequent relogin attempt, which would also leave the target inaccessible. Therefore fetch a fresh device->generation for the logout. Use memory barriers to prevent our plan being foiled by compiler or hardware optimizations.
