* [TG3]: Disable GPHY autopowerdownMatt Carlson2007-11-132-0/+12
| | | | | | | | | | New CPMU devices contend with the GPHY for power management. The GPHY autopowerdown feature is enabled by default in the PHY and thus needs to be disabled after every PHY reset.

* [TG3]: CPMU adjustments for loopback testsMatt Carlson2007-11-131-5/+7
| | | | | | | | | | This patch adds the LINK_SPEED mode to the list of CPMU modes that can cause the loopback tests to fail. These bugs are planned to be fixed in future revisions of the chip, so the patch qualifies the fixes as such.

* [TG3]: Fix nvram selftest failuresMatt Carlson2007-11-132-6/+38
| | | | | | | | | | | | | Newer devices contain bootcode in the chip's private ROM area. This bootcode is called selfboot. Selfboot can be patched in the device's NVRAM and the patches can have several formats. In one particular format, the checksum calculation needs to be slightly modified. This patch adjusts the NVRAM test code for that case, and add support for the missing formats.

| | | | | | | | | | 5784 and 5764 devices lock up when the link speed is 10Mbps, the CPMU link speed mode is enabled, and the MAC clock is running at 1.5Mhz.

* [TG3]: 5784 / 5764 GPHY power down fixMatt Carlson2007-11-132-3/+32
| | | | | | | | | | | | | | 5784 and 5764 devices fail to link / pass traffic after one load / unload cycle. This happens because of a hardware bug in the new CPMU. During normal operation, the MAC depends on the PHY clock being available. When the PHY is powered down, the clock the MAC depends on is disabled. The fix is to switch the MAC clock to an alternate source before powering down the PHY, and to restore the MAC clock to the PHY source upon device resume.

* [TG3]: Fix 5761 PXEboot crashMatt Carlson2007-11-131-23/+23
| | | | | | | | | | | | | | | | When 5761 devices boot the machine using PXEboot, PXE leaves the device active when it terminates. The tg3 driver has code to detect this condition and resets the device during initialization. On 5761 devices, device resets involve sending a driver state update message to the APE on the 5761. However, during this initialization stage, communications to the APE registers have not yet been set up. The driver then dereferences a NULL pointer and crashes the machine. The fix is to move the APE register access setup earlier in the initialization code to cover this condition.

| * Fix memory leak in discard case of sctp_sf_abort_violation()Jesper Juhl2007-11-121-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In net/sctp/sm_statefuns.c::sctp_sf_abort_violation() we may leak the storage allocated for 'abort' by returning from the function without using or freeing it. This happens in case "sctp_auth_recv_cid(SCTP_CID_ABORT, asoc)" is true and we jump to the 'discard' label. Spotted by the Coverity checker. The simple fix is to simply move the creation of the "abort chunk" to after the possible jump to the 'discard' label. This way we don't even have to allocate the memory at all in the problem case.

| * SCTP: Always flush the queue when uncorcking.Vlad Yasevich2007-11-091-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the code calls uncork, trigger a queue flush, even if the queue was not corked. Most callers that explicitely cork the queue will have additinal checks to see if they corked it. Callers who do not cork the queue expect packets to flow when they call uncork. The scneario that showcased this bug happend when we were not able to bundle DATA with outgoing COOKIE-ECHO. As a result the data just sat in the outqueue and did not get transmitted. The application expected a response, but nothing happened. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a possible race condition where the timer code will free the association and the next packet in the queue will also attempt to free the same association. The example is, when we receive an ABORT at about the same time as the retransmission timer fires. If the timer wins the race, it will free the association. Once it releases the lock, the queue processing will recieve the ABORT and will try to free the association again. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>

| * SCTP: Fix difference cases of retransmit.Vlad Yasevich2007-11-078-22/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d0ce92910bc04e107b2f3f2048f07e94f570035d broke several retransmit cases including fast retransmit. The reason is that we should only delay by rto while doing retranmists as a result of a timeout. Retransmit as a result of path mtu discover, fast retransmit, or other evernts that should trigger immidiate retransmissions got broken. Also, since rto is doubled prior to marking of packets elegable for retransmission, we never marked correct chunks anyway. The fix is provide a reason for a given retransmission so that we can mark chunks appropriately and to save the old rto value to do comparisons against. All regressions tests passed with this code.

* | [SUNGEM]: Fix suspend regression due to NAPI changes.Johannes Berg2007-11-131-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit bea3348e (the NAPI changes) made sungem unconditionally enable NAPI when resuming and unconditionally disable when suspending, this, however, makes napi_disable() hang when suspending when the interface was taken down before suspend because taking the interface down also disables NAPI. This patch makes touching the napi struct in suspend/resume code paths depend on having the interface up, thereby fixing the hang on suspend. The patch also moves the napi_disable() in gem_close() under the lock so that the NAPI state is always modified atomically together with the "opened" variable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While a signal is blocked, it must be posted even if its action is SIG_IGN or is SIG_DFL with the default action to ignore. This works right most of the time, but is broken when a sigwait (rt_sigtimedwait) is in progress. This changes the early-discard check to respect real_blocked. ~blocked is the set to check for "should wake up now", but ~(blocked|real_blocked) is the set for "blocked" semantics as defined by POSIX.

* | nfsd4: recheck for secure ports in fh_verifyJ. Bruce Fields2007-11-121-17/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As with commit 7fc90ec93a5eb71f4b08403baf5ba7176b3ec6b1 ("knfsd: nfsd: call nfsd_setuser() on fh_compose(), fix nfsd4 permissions problem") this is a case where we need to redo a security check in fh_verify() even though the filehandle already has an associated dentry--if the filehandle was created by fh_compose() in an earlier operation of the nfsv4 compound, then we may not have done these checks yet. Without this fix it is possible, for example, to traverse from an export without the secure ports requirement to one with it in a single compound, and bypass the secure port check on the new export. While we're here, fix up some minor style problems and change a printk() to a dprintk(), to make it harder for random unprivileged users to spam the logs. Signed-off-by: J.

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.

| * | | | [UNIX]: The unix_nr_socks limit can be exceededPavel Emelyanov2007-11-111-3/+4

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.

| * | | | [AF_UNIX]: Convert socks to unix_socks in scan_inflight, not in callbacksPavel Emelyanov2007-11-111-11/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
