this patch fixes a bug that occurs when routing packets and simultaneously changing the mtu. the rx_buffer_len variable is used during the rx cleanup and if that changes on the fly without stopping traffic bad things happen Signed-off-by:

1) 82544 does not need last_tx_tso workaround, it interferes with the 82544 workaround too 2) 82544 hang workaround was using the address of the page struct instead of the physical address as its "workaround decider" not sure how that ever worked Signed-off-by:

this patch is the first in a series of clean up patches for e1000 to drop unused code, and update the driver to kernel spec, and then, to update the driver to have all available bug fixes. Call it the e1000 weight loss plan. Signed-off-by:

Though, there are few other issues with suspend/resume in this driver. The intention of calling free_irq() in suspend() was to avoid any possible spurious interrupts (see commit 5b039e68 "3c59x PM fixes"). But, - On resume, the driver was requesting IRQ just after pci_set_master(), but before vortex_up() (which actually resets 3c59x chips). - Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy HW won't trigger spurious interrupts in another driver that requested the same interrupt. So, if we want to protect from unexpected interrupts, then on suspend we should issue disable_irq(), not free_irq(). Signed-off-by:

It seems recursion field from "struct ip_tunnel" is not anymore needed. recursion prevention is done at the upper level (in dev_queue_xmit()), since we use HARD_TX_LOCK protection for tunnels. This avoids a cache line ping pong on "struct ip_tunnel" : This structure should be now mostly read on xmit and receive paths. Signed-off-by:

Previous update did not resched in inner loop causing watchdogs. Rewrite inner loop to: * account for delays better with less clock calls * more accurate timing of delay: - only delay if packet was successfully sent - if delay is 100ns and it takes 10ns to build packet then account for that * use wait_event_interruptible_timeout rather than open coding it.

Due to man page of setsockopt, if optlen is not valid, kernel should return -EINVAL. But a simple testcase as following, errno is 0, which means setsockopt is successful. addr.s_addr = inet_addr("192.1.2.3"); setsockopt(s, IPPROTO_IP, IP_MULTICAST_IF, &addr, 1); printf("errno is %d\n", errno); Xiaotian Feng(dfeng@redhat.com) caught the bug. We fix it firstly checking the availability of optlen and then dealing with the logic like other options. Reported-by:Xiaotian Feng <dfeng@redhat.com> Signed-off-by:

The general one handles NULL, the static obsolescent (CONFIG_HAVE_LEGACY_PER_CPU_AREA) one in module.c doesn't; Eric's commit 720eba31 assumed it did, and various frobbings since then kept that assumption. All other callers in module.c all protect it with an if; this effectively does the same as free_init is only goto if we fail percpu_modalloc(). Reported-by:

Some boot mechanisms require that kernel parameters are stored in a separate file which is loaded to memory without further processing (e.g. the "Load from FTP" method on s390). When such a file contains newline characters, the kernel parameter preceding the newline might not be correctly parsed (due to the newline being stuck to the end of the actual parameter value) which can lead to boot failures. This patch improves kernel command line usability in such a situation by allowing generic whitespace characters as separators between kernel parameters. Signed-off-by:
