2015-08-17ipv6: Fix a potential deadlock when creating pcpu rtMartin KaFai Lau2-11/+35
rt6_make_pcpu_route() is called under read_lock(&table->tb6_lock). rt6_make_pcpu_route() calls ip6_rt_pcpu_alloc(rt) which then calls dst_alloc(). dst_alloc() _may_ call ip6_dst_gc() which takes the write_lock(&tabl->tb6_lock). A visualized version: read_lock(&table->tb6_lock); rt6_make_pcpu_route(); => ip6_rt_pcpu_alloc(); => dst_alloc(); => ip6_dst_gc(); => write_lock(&table->tb6_lock); /* oops */ The fix is to do a read_unlock first before calling ip6_rt_pcpu_alloc().

2015-08-17regulator: core: Define regulator_set_voltage_triplet()Viresh Kumar1-0/+10
Voltage tolerance isn't necessarily same on both sides of the target voltage and regulator_set_voltage_tol() wouldn't be suitable in such cases. Add another routine regulator_set_voltage_triplet(), which accepts target, min and max voltages as arguments. This first tries to set the voltage between the target voltage and the upper limit, then fall back on the full range. The idea behind this is to set regulator's voltage as close to the target voltage, as possible. Based on regulator_set_voltage_tol().

2015-08-17ppp: fix device unregistration upon netns deletionGuillaume Nault1-36/+42
PPP devices may get automatically unregistered when their network namespace is getting removed. This happens if the ppp control plane daemon (e.g. pppd) exits while it is the last user of this namespace. This leads to several races: * ppp_exit_net() may destroy the per namespace idr (pn->units_idr) before all file descriptors were released. Successive ppp_release() calls may then cleanup PPP devices with ppp_shutdown_interface() and try to use the already destroyed idr. * Automatic device unregistration may also happen before the ppp_release() call for that device gets executed. Once called on the file owning the device, ppp_release() will then clean it up and try to unregister it a second time. To fix these issues, operations defined in ppp_shutdown_interface() are moved to the PPP device's ndo_uninit() callback. This allows PPP devices to be properly cleaned up by unregister_netdev() and friends. So checking for ppp->owner is now an accurate test to decide if a PPP device should be unregistered. Setting ppp->owner is done in ppp_create_interface(), before device registration, in order to avoid unprotected modification of this field. Finally, ppp_exit_net() now starts by unregistering all remaining PPP devices to ensure that none will get unregistered after the call to idr_destroy().

2015-08-17Revert "net: limit tcp/udp rmem/wmem to SOCK_{RCV,SND}BUF_MIN"Calvin Owens1-6/+4
Commit 8133534c760d4083 ("net: limit tcp/udp rmem/wmem to SOCK_{RCV,SND}BUF_MIN") modified four sysctls to enforce that the values written to them are not less than SOCK_MIN_{RCV,SND}BUF. That change causes 4096 to no longer be accepted as a valid value for 'min' in tcp_wmem and udp_wmem_min. 4096 has been the default for both of those sysctls for a long time, and unfortunately seems to be an extremely popular setting. This change breaks a large number of sysctl configurations at Facebook. That commit referred to b1cb59cf2efe7971 ("net: sysctl_net_core: check SNDBUF and RCVBUF for min length"), which choose to use the SOCK_MIN constants as the lower limits to avoid nasty bugs. But AFAICS, a limit of SOCK_MIN_SNDBUF isn't necessary to do that: the BUG_ON cited in the commit message seems to have happened because unix_stream_sendmsg() expects a minimum of a full page (ie SK_MEM_QUANTUM) and the math broke, not because it had less than SOCK_MIN_SNDBUF allocated. This particular issue doesn't seem to affect TCP however: using a setting of "1 1 1" for tcp_{r,w}mem works, although it's obviously suboptimal. SK_MEM_QUANTUM would be a nice minimum, but it's 64K on some archs, so there would still be breakage. Since a value of one doesn't seem to cause any problems, we can drop the minimum 8133534c added to fix this. This reverts commit 8133534c760d4083f79d2cde42c636ccc0b2792e.

2015-08-17time: Always make sure wall_to_monotonic isn't positiveWang YanQing1-3/+10
Two issues were found on an IMX6 development board without an enabled RTC device(resulting in the boot time and monotonic time being initialized to 0). Issue 1:exportfs -a generate: "exportfs: /opt/nfs/arm does not support NFS export" Issue 2:cat /proc/stat: "btime 4294967236" The same issues can be reproduced on x86 after running the following code: int main(void) { struct timeval val; int ret; val.tv_sec = 0; val.tv_usec = 0; ret = settimeofday(&val, NULL); return 0; } Two issues are different symptoms of same problem: The reason is a positive wall_to_monotonic pushes boot time back to the time before Epoch, and getboottime will return negative value. In symptom 1: negative boot time cause get_expiry() to overflow time_t when input expire time is 2147483647, then cache_flush() always clears entries just added in ip_map_parse. In symptom 2: show_stat() uses "unsigned long" to print negative btime value returned by getboottime. This patch fix the problem by prohibiting time from being set to a value which would cause a negative boot time. As a result one can't set the CLOCK_REALTIME time prior to (1970 + system uptime).

2015-08-17time: Fix nanosecond file time rounding in timespec_trunc()Karsten Blees1-14/+8
timespec_trunc() avoids rounding if granularity <= nanoseconds-per-jiffie (or TICK_NSEC). This optimization assumes that: 1. current_kernel_time().tv_nsec is already rounded to TICK_NSEC (i.e. with HZ=1000 you'd get 1000000, 2000000, 3000000... but never 1000001). This is no longer true (probably since hrtimers introduced in 2.6.16). 2. TICK_NSEC is evenly divisible by all possible granularities. This may be true for HZ=100, 250, 1000, but obviously not for HZ=300 / TICK_NSEC=3333333 (introduced in 2.6.20). Thus, sub-second portions of in-core file times are not rounded to on-disk granularity. I.e. file times may change when the inode is re-read from disk or when the file system is remounted. This affects all file systems with file time granularities > 1 ns and < 1s, e.g. CEPH (1000 ns), UDF (1000 ns), CIFS (100 ns), NTFS (100 ns) and FUSE (configurable from user mode via struct fuse_init_out.time_gran). Steps to reproduce with e.g. UDF: $ dd if=/dev/zero of=udfdisk count=10000 && mkudffs udfdisk $ mkdir udf && mount udfdisk udf $ touch udf/test && stat -c %y udf/test 2015-06-09 10:22:56.130006767 +0200 $ umount udf && mount udfdisk udf $ stat -c %y udf/test 2015-06-09 10:22:56.130006000 +0200 Remounting truncates the mtime to 1 µs. Fix the rounding in timespec_trunc() and update the documentation. timespec_trunc() is exclusively used to calculate inode's [acm]time (mostly via current_fs_time()), and always with super_block.s_time_gran as second argument. So this can safely be changed without side effects. Note: This does _not_ fix the issue for FAT's 2 second mtime resolution, as super_block.s_time_gran isn't prepared to handle different ctime / mtime / atime resolutions nor resolutions > 1 second.

2015-08-17timer_list: Add the base offset so remaining nsecs are accurate for non ↵John Stultz1-1/+1
monotonic timers I noticed for non-monotonic timers in timer_list, some of the output looked a little confusing. For example: #1: <0000000000000000>, posix_timer_fn, S:01, hrtimer_start_range_ns, leap-a-day/2360 # expires at 1434412800000000000-1434412800000000000 nsecs [in 1434410725062375469 to 1434410725062375469 nsecs] You'll note the relative time till the expiration "[in xxx to yyy nsecs]" is incorrect. This is because its printing the delta between CLOCK_MONOTONIC time to the CLOCK_REALTIME expiration. This patch fixes this issue by adding the clock offset to the "now" time which we use to calculate the delta.

2015-08-17dmaengine: fix balance of privatecnt inc/dec operationsRobert Baldyga1-0/+4
This patch increments privatecnt value and set DMA_PRIVATE in device caps in dma_request_slave_channel() function. This is needed to keep privatecnt increment/decrement balance. As function dma_release_channel() decrements privatecnt counter, we need to increment it when channel is requested. Otherwise privatecnt drops into negatives after few dma_release_channel() calls.

Pull crypto fixes from Herbert Xu: "This fixes the following issues: - a regression caused by the conversion of IPsec ESP to the new AEAD interface: ESN with authencesn no longer works because it relied on the AD input SG list having a specific layout which is no longer the case. In linux-next authencesn is fixed properly and no longer assumes anything about the SG list format. While for this release a minimal fix is applied to authencesn so that it works with the new linear layout. - fix memory corruption caused by bogus index in the caam hash code. - fix powerpc nx SHA hashing which could cause module load failures if module signature verification is enabled" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: caam - fix memory corruption in ahash_final_ctx crypto: nx - respect sg limit bounds when building sg lists for SHA crypto: authencesn - Fix breakage with new ESP code
2015-08-17perf tools: Take Intel PT into useAdrian Hunter6-3/+649
To record an AUX area, the weak function auxtrace_record__init() must be implemented. Equally to decode an AUX area, the AUX area tracing type must be added to the perf_event__process_auxtrace_info() function. This patch makes those two changes plus hooks up default config for the intel_pt PMU. Also some brief documentation is provided for using the tools with intel_pt.

2015-08-17perf tools: Add Intel PT supportAdrian Hunter5-0/+2717
Add support for Intel Processor Trace. Intel PT support fits within the new auxtrace infrastructure. Recording is supporting by identifying the Intel PT PMU, parsing options and setting up events. Decoding is supported by queuing up trace data by cpu or thread and then decoding synchronously delivering synthesized event samples into the session processing for tools to consume.

2015-08-17perf tools: Add Intel PT decoderAdrian Hunter3-1/+1921
Add support for decoding an Intel Processor Trace. Intel PT trace data must be 'decoded' which involves walking the object code and matching the trace data packets. The decoder requests a buffer of binary data via a get_trace() call-back, which it decodes using instruction information which it gets via another call-back walk_insn().

2015-08-17perf tools: Add Intel PT logAdrian Hunter3-1/+208
Add a facility to log Intel Processor Trace decoding. The log is intended for debugging purposes only. The log file name is "intel_pt.log" and is opened in the current directory. The log contains a record of all packets and instructions decoded and can get very large (10 MB would be a small one).

2015-08-17perf tools: Add Intel PT instruction decoderAdrian Hunter12-3/+2803
Add support for decoding instructions for Intel Processor Trace. The kernel x86 instruction decoder is copied for this. This essentially provides intel_pt_get_insn() which takes a binary buffer, uses the kernel's x86 instruction decoder to get details of the instruction and then categorizes it for consumption by an Intel PT decoder.
