2011-01-25TCP: fix a bug that triggers large number of TCP RST by mistakeJerry Chu
This patch fixes a bug that causes TCP RST packets to be generated on otherwise correctly behaved applications, e.g., no unread data on close,..., etc. To trigger the bug, at least two conditions must be met: 1. The FIN flag is set on the last data packet, i.e., it's not on a separate, FIN only packet. 2. The size of the last data chunk on the receive side matches exactly with the size of buffer posted by the receiver, and the receiver closes the socket without any further read attempt. This bug was first noticed on our netperf based testbed for our IW10 proposal to IETF where a large number of RST packets were observed. netperf's read side code meets the condition 2 above 100%. Before the fix, tcp_data_queue() will queue the last skb that meets condition 1 to sk_receive_queue even though it has fully copied out (skb_copy_datagram_iovec()) the data. Then if condition 2 is also met, tcp_recvmsg() often returns all the copied out data successfully without actually consuming the skb, due to a check "if ((chunk = len - tp->ucopy.len) != 0) {" and "len -= chunk;" after tcp_prequeue_process() that causes "len" to become 0 and an early exit from the big while loop. I don't see any reason not to free the skb whose data have been fully consumed in tcp_data_queue(), regardless of the FIN flag. We won't get there if MSG_PEEK is on. Am I missing some arcane cases related to urgent data? Signed-off-by: H.K. Jerry Chu <hkchu@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

commit a8b690f98baf9fb19 (tcp: Fix slowness in read /proc/net/tcp) introduced a bug in handling of SYN_RECV sockets. st->offset represents number of sockets found since beginning of listening_hash[st->bucket]. We should not reset st->offset when iterating through syn_table[st->sbucket], or else if more than ~25 sockets (if PAGE_SIZE=4096) are in SYN_RECV state, we exit from listening_get_next() with a too small st->offset Next time we enter tcp_seek_last_pos(), we are not able to seek past already found sockets.

2011-01-24GRO: fix merging a paged skb after non-paged skbsMichal Schmidt
Suppose that several linear skbs of the same flow were received by GRO. They were thus merged into one skb with a frag_list. Then a new skb of the same flow arrives, but it is a paged skb with data starting in its frags[]. Before adding the skb to the frag_list skb_gro_receive() will of course adjust the skb to throw away the headers. It correctly modifies the page_offset and size of the frag, but it leaves incorrect information in the skb: ->data_len is not decreased at all. ->len is decreased only by headlen, as if no change were done to the frag. Later in a receiving process this causes skb_copy_datagram_iovec() to return -EFAULT and this is seen in userspace as the result of the recv() syscall. In practice the bug can be reproduced with the sfc driver. By default the driver uses an adaptive scheme when it switches between using napi_gro_receive() (with skbs) and napi_gro_frags() (with pages). The bug is reproduced when under rx load with enough successful GRO merging the driver decides to switch from the former to the latter. Manual control is also possible, so reproducing this is easy with netcat: - on machine1 (with sfc): nc -l 12345 > /dev/null - on machine2: nc machine1 12345 < /dev/zero - on machine1: echo 1 > /sys/module/sfc/parameters/rx_alloc_method # use skbs echo 2 > /sys/module/sfc/parameters/rx_alloc_method # use pages - See that nc has quit suddenly.

2011-01-24can: at91_can: make can_id of mailbox 0 configurableMarc Kleine-Budde
Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in "AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the contents of mailbox 0 may be send under certain conditions (even if disabled or in rx mode). The workaround in the errata suggests not to use the mailbox and load it with an unused identifier. This patch implements the second part of the workaround. A sysfs entry "mb0_id" is introduced. While the interface is down it can be used to configure the can_id of mailbox 0. The default value id 0x7ff. In order to use an extended can_id add the CAN_EFF_FLAG (0x80000000U) to the can_id. Example: - standard id 0x7ff: echo 0x7ff > /sys/class/net/can0/mb0_id - extended id 0x1fffffff: echo 0x9fffffff > /sys/class/net/can0/mb0_id Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Acked-by: Wolfgang Grandegger <wg@grandegger.com> Acked-by: Kurt Van Dijck <kurt.van.dijck@eia.be> For the Documentation-part: Acked-by: Wolfram Sang <w.sang@pengutronix.de>

2011-01-24sched: Fix poor interactivity on UP systems due to group scheduler nice tune bugYong Zhang
Michael Witten and Christian Kujau reported that the autogroup scheduling feature hurts interactivity on their UP systems. It turns out that this is an older bug in the group scheduling code, and the wider appeal provided by the autogroup feature exposed it more prominently. When on UP with FAIR_GROUP_SCHED enabled, tune shares only affect tg->shares, but is not reflected in tg->se->load. The reason is that update_cfs_shares() does nothing on UP. So introduce update_cfs_shares() for UP && FAIR_GROUP_SCHED. This issue was found when enable autogroup scheduling was enabled, but it is an older bug that also exists on cgroup.cpu on UP.

2011-01-24BUILD_BUG_ON: make it handle more casesRusty Russell
BUILD_BUG_ON used to use the optimizer to do code elimination or fail at link time; it was changed to first the size of a negative array (a nicer compile time error), then (in 8c87df457cb58fe75b9b893007917cf8095660a0) to a bitfield. This forced us to change some non-constant cases to MAYBE_BUILD_BUG_ON(); as Jan points out in that commit, it didn't work as intended anyway. bitfields: needs a literal constant at parse time, and can't be put under "if (__builtin_constant_p(x))" for example. negative array: can handle anything, but if the compiler can't tell it's a constant, silently has no effect. link time: breaks link if the compiler can't determine the value, but the linker output is not usually as informative as a compiler error. If we use the negative-array-size method *and* the link time trick, we get the ability to use BUILD_BUG_ON() under __builtin_constant_p() branches, and maximal ability for the compiler to detect errors at build time. We also document it thoroughly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Jan Beulich <JBeulich@novell.com> Acked-by: Hollis Blanchard <hollisb@us.ibm.com>

Currently only drivers that are built as modules have their versions shown in /sys/module/<module_name>/version, but this information might also be useful for built-in drivers as well. This especially important for drivers that do not define any parameters - such drivers, if built-in, are completely invisible from userspace.

If we use jump table in module init, there are marked as removed in __jump_table section after init is done. But we already applied ro permissions on the module, so we can't modify a read only section (crash in remove_jump_label_module_init). Make the __jump_table section rw.

2011-01-22perf tools: Fix time function double declaration with glibcThomas Renninger
It's enough to include the local "debug.h" file to trigger it. man time reveals this is already declared in glibc: time - get time in seconds -> rename the variable.

2011-01-22perf tools: Fix build by checking if extra warnings are supportedArnaldo Carvalho de Melo
The -Wstack-protector and -Wvolatile-register-var warnings, for instance, are not supported by gcc 3.4.6. So fix by doing the same check we already do for -fstack-protector-all. With this and the other patches in this series, perf builds unmodified on, for instance, RHEL4.

We need the definiton for __always_inline in bitops.h to fix the build on distros where it isn't available or compiler.h doesn't get included indirectly.

2011-01-22perf tools: Fix 64 bit integer format stringsArnaldo Carvalho de Melo
Using %L[uxd] has issues in some architectures, like on ppc64. Fix it by making our 64 bit integers typedefs of stdint.h types and using PRI[ux]64 like, for instance, git does. Reported by Denis Kirjanov that provided a patch for one case, I went and changed all cases.
