Ensure that the content of these sysfs files is always less than one page. Even if this means truncating. The files in question are scheduled to be moved over to debugfs in the future anyway.

However, that should not happen. This fixes this problem and it changes the prototype of netlink_set_err() to return the number of sockets that have set the NETLINK_RECV_NO_ENOBUFS socket option.

This appears to be because the NET_DMA design queues up lots of memcpy operations, but doesn't issue or wait for them (and thus free the associated skbs) until it is time for tcp_recvmesg() to return. The socket hangs when its TCP window goes to zero before enough data is available to satisfy the read. Periodically issue asynchronous memcpy operations, and free skbs for ones that have completed, to prevent sockets from going into zero-window mode. Signed-off-by: Steven J.

They accumulate to the maximum value and then roll over. They are also not cleared when the VF executes a soft reset, so it is possible they are non-zero when the driver loads and starts. This has all been accounted for in the code that keeps the stats up to date but there is one case that is not. When the PF driver is reset the counters in the VF are all reset to zero. This adds an additional accounting overhead into the VF driver when the PF is reset under its feet. This patch adds additional counters that are used by the VF driver to accumulate and save stats after a PF reset has been detected. Prior to this patch displaying the stats in the VF after the PF has reset would show bogus data.

The only way to renew xfrm_dst when the underlying route has changed, is to implement dst_check for this. This is what ipv6 side does too. The problems started after 87c1e12b5eeb7b30b4b41291bef8e0b41fc3dde9 ("ipsec: Fix bogus bundle flowi") which fixed a bug causing xfrm_dst to not get reused, until that all lookups always generated new xfrm_dst with new route reference and path mtu worked. But after the fix, the old routes started to get reused even after they were expired causing pmtu to break (well it would occationally work if the rtable gc had run recently and marked the route obsolete causing dst_check to get called).

Out of concern about crypto incompatibility issues, this change was merged instead: commit 6c8afef551fef87a3bf24f8a74c69a7f2f72fc82 Author: Sujith <Sujith.Manoharan@atheros.com> Date: Tue Feb 9 10:07:00 2010 +0530 ath9k: Fix sequence numbers for PAE frames After a lot of testing, I'm able to reliably trigger a driver crash on rekeying with current versions with this change in place. It seems that the driver does not support sending out regular MPDUs with the same TID while an A-MPDU session is active. This leads to duplicate entries in the TID Tx buffer, which hits the following BUG_ON in ath_tx_addto_baw(): index = ATH_BA_INDEX(tid->seq_start, bf->bf_seqno); cindex = (tid->baw_head + index) & (ATH_TID_MAX_BUFS - 1); BUG_ON(tid->tx_buf[cindex] != NULL); I believe until we actually have a reproducible case of an incompatibility with another AP using no PAE special cases, we should simply get rid of this mess. This patch completely fixes my crash issues in STA mode and makes it stay connected without throughput drops or connectivity issues even when the AP is configured to a very short group rekey interval.

Commit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 ("Add generic sys_ipc wrapper") changed the second argument from an unsigned long to an int. When we call shmget the system call wrappers for sys_ipc will sign extend second (ie the size) which truncates it. It took a while to track down because the call succeeds and strace shows the untruncated size :) The patch below changes second from an int to an unsigned long which fixes shmget on ppc64 (and I assume s390, sparc64 and mips64). Signed-off-by: Anton Blanchard <anton@samba.org> -- I assume the function prototypes for the other IPC methods would cause us to sign or zero extend second where appropriate (avoiding any security issues). Come to think of it, the syscall wrappers for each method should do that for us as well. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The problem is that cpuhw->amd_nb may be NULL already, so the function should make sure it's not NULL before accessing the object pointed to by it. Signed-off-by: Rafael J.
