When the TSC is calibrated against the PIT due to the nonavailability of PMTIMER/HPET or due to SMI interference then the setup of the per CPU cyc2ns variables is skipped. This is unlikely to happen but it would definitely render sched_clock() unusable. This was introduced with commit 53d517cd x86: scale cyc_2_nsec according to CPU frequency Update the per CPU cyc2ns variables in all exit pathes of tsc_calibrate. Signed-off-by:

When we fully commit to returning back to kernel mode from a trap, zero out the regs->magic value to prevent false positives during stack backtraces. Signed-off-by:David S. Miller <davem@davemloft.net>

The offset to the pt_regs area was wrong, so we weren't looking at the right location for the magic cookie. A trap frame is composed of a "struct sparc_stackf" then a "struct pt_regs", the code was using "struct reg_window" instead of "struct sparc_stackf". Signed-off-by: -

Because of the silly way I set up the initial stack for new kernel threads, there is a loop at the top of the stack. To fix this, properly add another stack frame that is copied from the parent and terminate it in the child by setting the frame pointer in that frame to zero. Signed-off-by: -

Unless there will be any objection here, I suggest consider the following patch which simply removes the code for the -DI_WISH_WORLD_WERE_PERFECT in the three methods which use it. The compilation errors we get when using -DI_WISH_WORLD_WERE_PERFECT show that this code was not built and not used for really a long time. Signed-off-by:

If previous window was above representable values of u16, strange things will happen if undo with the truncated value is called for. Alternatively, this could be fixed by some max trickery but that would limit undoing high-speed undos. Adds 16-bit hole but there isn't anything to fill it with. Signed-off-by:

Here the local hexbuf is a duplicate of global const char hex_asc from lib/hexdump.c, except the hex letters' cases: const char hexbuf[] = "0123456789ABCDEF"; const char hex_asc[] = "0123456789abcdef"; and here to print HW addresses, the hex cases are not significant. Thanks to Harvey Harrison to introduce the hex_asc_hi/hex_asc_lo helpers. Signed-off-by:

According to David Monro, at least with Natsemi Saturn chips the cassini driver has some trouble with ipv6 checksums. Until we have more information about what's going on here, only use the chip checksums for ipv4. This workaround was suggested and tested by David. Update version and release date. Signed-off-by:

We are seeing an issue with TCP in handling an ICMP frag needed message that is received after net.ipv4.tcp_retries1 retransmits. The default value of retries1 is 3. So if the path mtu changes and ICMP frag needed is lost for the first 3 retransmits or if it gets delayed until 3 retransmits are done, TCP doesn't update MSS correctly and continues to retransmit the orginal message until it timesout after tcp_retries2 retransmits. I am seeing this issue even with the latest 2.6.25.4 kernel. In tcp_retransmit_timer(), when retransmits counter exceeds tcp_retries1 value, the dst cache entry of the socket is reset. At this time, if we receive an ICMP frag needed message, the dst entry gets updated with the new MTU, but the TCP sockets dst_cache entry remains NULL. So the next time when we try to retransmit after the ICMP frag needed is received, tcp_retransmit_skb() gets called. Here the cur_mss value is calculated at the start of the routine with a NULL sk_dst_cache. Instead we should call tcp_current_mss after the rebuild_header that caches the dst entry with the updated mtu. Also the rebuild_header should be called before tcp_fragment so that skb is fragmented if the mss goes down. Signed-off-by:

Greg Steuck <greg@nest.cx> points out that some of the netfilter headers can't be used in userspace without including linux/types.h first. The headers include their own linux/types.h include statements, these are stripped by make headers-install because they are inside #ifdef __KERNEL__ however. Move them out to fix this.
