2011-02-11drivers/w1/masters/omap_hdq.c: add missing clk_putJulia Lawall1-14/+14
This code makes two calls to clk_get, then test both return values and fails if either failed. The problem is that in the first inner if, where the first call to clk_get has failed, it don't know if the second call has failed as well. So it don't know whether clk_get should be called on the result of the second call. Of course, it would be possible to test that value again. A simpler solution is just to test the result of calling clk_get directly after each call. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ position p1,p2; expression e; statement S; @@ e = clk_get@p1(...) ... if@p2 (IS_ERR(e)) S @@ expression e; statement S; identifier l; position r.p1, p2 != r.p2; @@ *e = clk_get@p1(...) ... when != clk_put(e) *if@p2 (...) { ... when != clk_put(e) * return ...; }// </smpl> Signed-off-by: Julia Lawall <[email protected]> Cc: Evgeniy Polyakov <[email protected]> Acked-by: Tony Lindgren <[email protected]> Acked-by: Amit Kucheria <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2011-02-11vmscan: fix zone shrinking exit when scan work is doneJohannes Weiner1-2/+2
Commit 3e7d34497067 ("mm: vmscan: reclaim order-0 and use compaction instead of lumpy reclaim") introduced an indefinite loop in shrink_zone(). It meant to break out of this loop when no pages had been reclaimed and not a single page was even scanned. The way it would detect the latter is by taking a snapshot of sc->nr_scanned at the beginning of the function and comparing it against the new sc->nr_scanned after the scan loop. But it would re-iterate without updating that snapshot, looping forever if sc->nr_scanned changed at least once since shrink_zone() was invoked. This is not the sole condition that would exit that loop, but it requires other processes to change the zone state, as the reclaimer that is stuck obviously can not anymore. This is only happening for higher-order allocations, where reclaim is run back to back with compaction.

2011-02-11mlock: do not munlock pages in __do_fault()Michel Lespinasse1-6/+0
If the page is going to be written to, __do_page needs to break COW. However, the old page (before breaking COW) was never mapped mapped into the current pte (__do_fault is only called when the pte is not present), so vmscan can't have marked the old page as PageMlocked due to being mapped in __do_fault's VMA. Therefore, __do_fault() does not need to worry about clearing PageMlocked() on the old page.

2011-02-11mlock: fix race when munlocking pages in do_wp_page()Michel Lespinasse1-14/+12
vmscan can lazily find pages that are mapped within VM_LOCKED vmas, and set the PageMlocked bit on these pages, transfering them onto the unevictable list. When do_wp_page() breaks COW within a VM_LOCKED vma, it may need to clear PageMlocked on the old page and set it on the new page instead. This change fixes an issue where do_wp_page() was clearing PageMlocked on the old page while the pte was still pointing to it (as well as rmap). Therefore, we were not protected against vmscan immediately transfering the old page back onto the unevictable list. This could cause pages to get stranded there forever. I propose to move the corresponding code to the end of do_wp_page(), after the pte (and rmap) have been pointed to the new page. Additionally, we can use munlock_vma_page() instead of clear_page_mlock(), so that the old page stays mlocked if there are still other VM_LOCKED vmas mapping it.

2011-02-11nbd: remove module-level ioctl mutexSoren Hansen1-3/+0
Commit 2a48fc0ab242417 ("block: autoconvert trivial BKL users to private mutex") replaced uses of the BKL in the nbd driver with mutex operations.

However, that other ioctl blocks, waiting for the module-level mutex that replaced the BKL, and then we're stuck. This patch removes the module-level mutex altogether. It's clearly wrong, and as far as I can see, it's entirely unnecessary, since the nbd driver maintains per-device mutexes, and I don't see anything that would require a module-level (or kernel-level, for that matter) mutex.

2011-02-11ptrace: use safer wake up on ptrace_detach()Tejun Heo1-1/+1
The wake_up_process() call in ptrace_detach() is spurious and not interlocked with the tracee state. IOW, the tracee could be running or sleeping in any place in the kernel by the time wake_up_process() is called. This can lead to the tracee waking up unexpectedly which can be dangerous. The wake_up is spurious and should be removed but for now reduce its toxicity by only waking up if the tracee is in TRACED or STOPPED state. This bug can possibly be used as an attack vector. I don't think it will take too much effort to come up with an attack which triggers oops somewhere. Most sleeps are wrapped in condition test loops and should be safe but we have quite a number of places where sleep and wakeup conditions are expected to be interlocked. Although the window of opportunity is tiny, ptrace can be used by non-privileged users and with some loading the window can definitely be extended and exploited.

2011-02-11vfs: call rcu_barrier after ->kill_sb()Boaz Harrosh1-0/+5
In commit fa0d7e3de6d6 ("fs: icache RCU free inodes"), we use rcu free inode instead of freeing the inode directly. It causes a crash when we rmmod immediately after we umount the volume[1]. So we need to call rcu_barrier after we kill_sb so that the inode is freed before we do rmmod. The idea is inspired by Aneesh Kumar. rcu_barrier will wait for all callbacks to end before preceding. The original patch was done by Tao Ma, but synchronize_rcu() is not enough here. 1. http://marc.info/?l=linux-fsdevel&m=129680863330185&w=2 Tested-by: Tao Ma <[email protected]> Signed-off-by: Boaz Harrosh <[email protected]> Cc: Nick Piggin <[email protected]> Cc: Al Viro <[email protected]> Cc: Chris Mason <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2011-02-11Fix possible filp_cachep memory corruptionLinus Torvalds2-10/+12
In commit 31e6b01f4183 ("fs: rcu-walk for path lookup") we started doing path lookup using RCU, which then falls back to a careful non-RCU lookup in case of problems (LOOKUP_REVAL). So do_filp_open() has this "re-do the lookup carefully" looping case. However, that means that we must not release the open-intent file data if we are going to loop around and use it once more! Fix this by moving the release of the open-intent data to the function that allocates it (do_filp_open() itself) rather than the helper functions that can get called multiple times (finish_open() and do_last()). This makes the logic for the lifetime of that field much more obvious, and avoids the possible double free. Reported-by: J. R.

2011-02-11cifs: don't always drop malformed replies on the floor (try #3)Jeff Layton3-7/+28
Slight revision to this patch...use min_t() instead of conditional assignment. Also, remove the FIXME comment and replace it with the explanation that Steve gave earlier. After receiving a packet, we currently check the header. If it's no good, then we toss it out and continue the loop, leaving the caller waiting on that response. In cases where the packet has length inconsistencies, but the MID is valid, this leads to unneeded delays. That's especially problematic now that the client waits indefinitely for responses. Instead, don't immediately discard the packet if checkSMB fails. Try to find a matching mid_q_entry, mark it as having a malformed response and issue the callback.

2011-02-11tpm_tis: Use timeouts returned from TPMStefan Berger3-3/+21
The current TPM TIS driver in git discards the timeout values returned from the TPM. The check of the response packet needs to consider that the return_code field is 0 on success and the size of the expected packet is equivalent to the header size + u32 length indicator for the TPM_GetCapability() result + 3 timeout indicators of type u32. I am also adding a sysfs entry 'timeouts' showing the timeouts that are being used.

2011-02-10char/ipmi: fix OOPS caused by pnp_unregister_driver on unregistered driverCorey Minyard1-10/+2
This patch fixes an OOPS triggered when calling modprobe ipmi_si a second time after the first modprobe returned without finding any ipmi devices. This can happen if you reload the module after having the first module load fail. The driver was not deregistering from PNP in that case. Peter Huewe originally reported this patch and supplied a fix, I have a different patch based on Linus' suggestion that cleans things up a bit more.

2011-02-10cap_syslog: accept CAP_SYS_ADMIN for nowLinus Torvalds1-19/+35
In commit ce6ada35bdf7 ("security: Define CAP_SYSLOG") Serge Hallyn introduced CAP_SYSLOG, but broke backwards compatibility by no longer accepting CAP_SYS_ADMIN as an override (it would cause a warning and then reject the operation). Re-instate CAP_SYS_ADMIN - but keeping the warning - as an acceptable capability until any legacy applications have been updated. There are apparently applications out there that drop all capabilities except for CAP_SYS_ADMIN in order to access the syslog.
