* igb: use igb_free_q_vectors to cleanup failure in igb_alloc_q_vectorsNick Nunley2010-02-17
| | | | | | | | | | This change makes it so that igb_free_q_vectors is reused in igb_alloc_q_vectors to handle the cleanup instead of unwinding through the allocations.

The transmitter should not be turned off before all characters have been transmitted. serial8250_tx_empty() was reporting that all characters were transmitted before they actually were. === Discovered in parallel with more testing and analysis by Kees Schoenmakers as follows: I ran into an NetMos 9835 serial pci board which behaves a little different than the standard. This type of expansion board is very common. "Standard" 8250 compatible devices clear the 'UART_LST_TEMT" bit together with the "UART_LSR_THRE" bit when writing data to the device. The NetMos device does it slightly different I believe that the TEMT bit is coupled to the shift register. The problem is that after writing data to the device and very quickly after that one does call serial8250_tx_empty, it returns the wrong information. My patch makes the test more robust (and solves the problem) and it does not affect the already correct devices. Alan: We may yet need to quirk this but now we know which chips we have a way to do that should we find this breaks some other 8250 clone with dodgy THRE.

I think that the calling convention is fundamentally buggered. The caller is the one that did the "reap_as()" to get the as thing, the caller should be the one to free it too. Freeing it in the caller also means that it very clearly always gets freed, and avoids the need for any "free in the error case too".

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to only copy the data received by the device to userspace, not the whole kernel buffer, which can contain "stale" data. Thanks to Marcus Meissner for pointing this out and testing the fix.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is currently a bug in sysfs_sd_setattr inherited from sysfs_setattr in 2.6.32 where the first time we set the attributes on a sysfs file we allocate backing store but do not set the backing store attributes. Resulting in overly restrictive permissions on sysfs files. The fix is to simply modify the code so that it always executes when we update the sysfs attributes, as we did in 2.6.31 and earlier.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before sending a command to the ASIC, set version properly. This is necessary for the ARM firmware to send correct data to the driver. This also fixes a bug in certain skews of the ASIC where the statistics are misreported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xfrm_state_clone calls kfree instead of xfrm_state_put to free a failed state. Depending on the state of the failed state, it can cause leaks to things like module references. All states should be freed by xfrm_state_put past the point of xfrm_init_state.

| | * | ipcomp: Avoid duplicate calls to ipcomp_destroyHerbert Xu2010-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ipcomp_tunnel_attach fails we will call ipcomp_destroy twice. This may lead to double-frees on certain structures. As there is no reason to explicitly call ipcomp_destroy, this patch removes it from ipcomp*.c and lets the standard xfrm_state destruction take place. This is based on the discovery and patch by Alexey Dobriyan. Tested-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
