2007-11-12x86: fix taking DNA during 64bit sigreturnSiddha, Suresh B
restore sigcontext is taking a DNA exception while restoring FP context from the user stack, during the sigreturn. Appended patch fixes it by doing clts() if the app doesn't touch FP during the signal handler execution. This will stop generating a DNA, during the fxrstor in the sigreturn. This improves 64-bit lat_sig numbers by ~30% on my core2 platform. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-11-12core dump: remain dumpableRoland McGrath
The coredump code always calls set_dumpable(0) when it starts (even if RLIMIT_CORE prevents any core from being dumped). The effect of this (via task_dumpable) is to make /proc/pid/* files owned by root instead of the user, so the user can no longer examine his own process--in a case where there was never any privileged data to protect. This affects e.g. auxv, environ, fd; in Fedora (execshield) kernels, also maps. In practice, you can only notice this when a debugger has requested PTRACE_EVENT_EXIT tracing. set_dumpable was only used in do_coredump for synchronization and not intended for any security purpose. (It doesn't secure anything that wasn't already unsecured when a process dies by SIGTERM instead of SIGQUIT.) This changes do_coredump to check the core_waiters count as the means of synchronization, which is sufficient. Now we leave the "dumpable" bits alone.

2007-11-12virtio: Force use of power-of-two for descriptor ring sizesRusty Russell
The virtio descriptor rings of size N-1 were nicely set up to be aligned to an N-byte boundary. But as Anthony Liguori points out, the free-running indices used by virtio require that the sizes be a power of 2, otherwise we get problems on wrap (demonstrated with lguest). So we replace the clever "2^n-1" scheme with a simple "align to page boundary" scheme: this means that all virtio rings take at least two pages, but it's safer than guessing cache alignment. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-11-12lguest: Fix lguest virtio-blk backend size computationAnthony Liguori
This seems like an obvious typo but it's worked in the past because the virtio blk frontend just ignores the length field on completion. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-11-12virtio: Fix used_idx wrap-aroundAnthony Liguori
The more_used() function compares the vq->vring.used->idx with last_used_idx. Since vq->vring.used->idx is a 16-bit integer, and last_used_idx is an unsigned int, this results in unpredictable behavior when vq->vring.used->idx wraps around. This patch corrects this by changing last_used_idx to the correct type. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2007-11-12virtio: fix vring_init for 64 bitsAnthony Liguori
This patch fixes a typo in vring_init(). This happens to work today in lguest because the sizeof(struct vring_desc) is 16 and struct vring contains 3 pointers and an unsigned int so on 32-bit sizeof(struct vring_desc) == sizeof(struct vring). However, this is no longer true on 64-bit where the bug is exposed. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2007-11-10[INET]: Small possible memory leak in FIB rulesDenis V. Lunev
This patch fixes a small memory leak. Default fib rules can be deleted by the user if the rule does not carry FIB_RULE_PERMANENT flag, f.e. by ip rule flush Such a rule will not be freed as the ref-counter has 2 on start and becomes clearly unreachable after removal.

2007-11-10[UNIX]: The unix_nr_socks limit can be exceededPavel Emelyanov
The unix_nr_socks value is limited with the 2 * get_max_files() value, as seen from the unix_create1(). However, the check and the actual increment are separated with the GFP_KERNEL allocation, so this limit can be exceeded under a memory pressure - task may go to sleep freeing the pages and some other task will be allowed to allocate a new sock and so on and so forth. So make the increment before the check (similar thing is done in the sock_kmalloc) and go to kmalloc after this. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-11-10[AF_UNIX]: Convert socks to unix_socks in scan_inflight, not in callbacksPavel Emelyanov
The scan_inflight() routine scans through the unix sockets and calls some passed callback. The fact is that all these callbacks work with the unix_sock objects, not the sock ones, so make this conversion in the scan_inflight() before calling the callbacks. This removes one unneeded variable from the inc_inflight_move_tail(). Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-11-10mac80211: make "decrypt failed" messages conditional upon MAC80211_DEBUGJohn W. Linville
Make "decrypt failed" and "have no key" debugging messages compile conditionally upon CONFIG_MAC80211_DEBUG. They have been useful for finding certain problems in the past, but in many cases they just clutter a user's logs. A typical example is an enviornment where multiple SSIDs are using a single BSSID but with different protection schemes or different keys for each SSID. In such an environment these messages are just noise. Let's just leave them for those interested enough to turn-on debugging. Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-11-10mac80211: use IW_AUTH_PRIVACY_INVOKED rather than IW_AUTH_KEY_MGMTJohannes Berg
In the long bug-hunt for why dynamic WEP networks didn't work it turned out that mac80211 incorrectly uses IW_AUTH_KEY_MGMT while it should use IW_AUTH_PRIVACY_INVOKED to determine whether to associate to protected networks or not.

Replace mutex_lock_interruptible() by mutex_lock() in rfkill_register(), as interruptible doesn't make sense there.

2007-11-10iwlwifi: select proper rate control algorithmJohannes Berg
Prior to this patch, iwlwifi would always use the first registered rate control algorithm which, depending on system setup, could be anything. After the mac80211 patch to make the simple algorithm built-in, it would always be simple. This has always been a bug in iwlwifi.

2007-11-10mac80211: allow driver to ask for a rate control algorithmJohannes Berg

2007-11-10mac80211: don't allow registering the same rate control twiceJohannes Berg

2007-11-10mac80211: make simple rate control algorithm built-inJohannes Berg
Too frequently people do not have module autoloading enabled or fail to install the rate control module correctly, hence their hardware probing fails due to no rate control algorithm being available. This makes the 'simple' algorithm built into the mac80211 module unless EMBEDDED is enabled in which case it can be disabled (eg. if the wanted driver requires another rate control algorithm.)

2007-11-10[NET]: Fix skb_truesize_check() assertionChuck Lever
The intent of the assertion in skb_truesize_check() is to check for skb->truesize being decremented too much by other code, resulting in a wraparound below zero. The type of the right side of the comparison causes the compiler to promote the left side to an unsigned type, despite the presence of an explicit type cast. This defeats the check for negativity.

Move clearing outside skb processing loop so that it will get executed even if the skb loop terminates prematurely due to out-of-mem.

2007-11-10[TCP]: Fix reord detection due to snd_una covered holesIlpo Järvinen
Fixes subtle bug like the one with fastpath_cnt_hint happening due to the way the GSO and hints interact. Because hints are not reset when just a GSOed skb is partially ACKed, there's no guarantee that the relevant part of the write queue is going to be processed in sacktag at all (skbs below snd_una) because fastpath hint can fast forward the entrypoint. This was also on the way of future reductions in sacktag's skb processing. Also future cleanups in sacktag can be made after this (in 2.6.25). This may make reordering update in tcp_try_undo_partial redundant but I'm not too sure so I left it there. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.
