2018-02-08selftests/ftrace: Have reset_ftrace_filter handle modulesSteven Rostedt (VMware)
If a function probe in set_ftrace_filter belongs to a module, it will contain the module name. Like: wmi_query_block [wmi]:traceoff:unlimited But writing: '!wmi_query_block [wmi]:traceoff' > set_ftrace_filter will cause an error. We still need to write: '!wmi_query_block:traceoff' > set_ftrace_filter Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2018-02-08tracing: Fix parsing of globs with a wildcard at the beginningSteven Rostedt (VMware)
Al Viro reported: For substring - sure, but what about something like "*a*b" and "a*b"? AFAICS, filter_parse_regex() ends up with identical results in both cases - MATCH_GLOB and *search = "a*b". And no way for the caller to tell one from another. Testing this with the following: # cd /sys/kernel/tracing # echo '*raw*lock' > set_ftrace_filter bash: echo: write error: Invalid argument With this patch: # echo '*raw*lock' > set_ftrace_filter # cat set_ftrace_filter _raw_read_trylock _raw_write_trylock _raw_read_unlock _raw_spin_unlock _raw_write_unlock _raw_spin_trylock _raw_spin_lock _raw_write_lock _raw_read_lock Al recommended not setting the search buffer to skip the first '*' unless we know we are not using MATCH_GLOB. This implements his suggested logic.

2018-02-08ftrace: Remove incorrect setting of glob search fieldSteven Rostedt (VMware)
__unregister_ftrace_function_probe() will incorrectly parse the glob filter because it resets the search variable that was setup by filter_parse_regex(). Al Viro reported this: After that call of filter_parse_regex() we could have func_g.search not equal to glob only if glob started with '!' or '*'. In the former case we would've buggered off with -EINVAL (not = 1). In the latter we would've set func_g.search equal to glob + 1, calculated the length of that thing in func_g.len and proceeded to reset func_g.search back to glob. Suppose the glob is e.g. *foo*. We end up with func_g.type = MATCH_MIDDLE_ONLY; func_g.len = 3; func_g.search = "*foo"; Feeding that to ftrace_match_record() will not do anything sane - we will be looking for names containing "*foo" (->len is ignored for that one).

'nfp-fix-disabling-TC-offloads-in-flower-max-TSO-segs-and-module-version' Jakub Kicinski says: ==================== nfp: fix disabling TC offloads in flower, max TSO segs and module version This set corrects the way nfp deals with the NETIF_F_HW_TC flag. It has slipped the review that flower offload does not currently refuse disabling this flag when filter offload is active. nfp's flower offload does not actually keep track of how many filters for each port are offloaded. The accounting of the number of filters is added to the nfp core structures, and BPF moved to use these structures as well. If users are allowed to disable TC offloads while filters are active, not only is it incorrect behaviour, but actually the NFP will never be told to remove the flows, leading to use-after-free when stats arrive. Fourth patch makes sure we declare the max number of TSO segments. FW should drop longer packets cleanly (otherwise this would be a security problem for untrusted VFs) but dropping longer TSO frames is not nice and driver should prevent them from being generated. Last small addition populates MODULE_VERSION with kernel version. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2018-02-08nfp: forbid disabling hw-tc-offload on representors while offload activeJakub Kicinski
All netdevs which can accept TC offloads must implement .ndo_set_features(). nfp_reprs currently do not do that, which means hw-tc-offload can be turned on and off even when offloads are active. Whether the offloads are active is really a question to nfp_ports, so remove the per-app tc_busy callback indirection thing, and simply count the number of offloaded items in nfp_port structure.

2018-02-08nfp: don't advertise hw-tc-offload on non-port netdevsJakub Kicinski
nfp_port is a structure which represents an ASIC port, both PCIe vNIC (on a PF or a VF) or the external MAC port. vNIC netdev (struct nfp_net) and pure representor netdev (struct nfp_repr) both have a pointer to this structure. nfp_reprs always have a port associated. nfp_nets, however, only represent a device port in legacy mode, where they are considered the MAC port. In switchdev mode they are just the CPU's side of the PCIe link. By definition TC offloads only apply to device ports. Don't set the flag on vNICs without a port (i.e. in switchdev mode).

Reduce the window of opportunity for set-wedged being called concurrently with reset (after i915_reset() has performed the i915_gem_unset_wedged()) by moving the set_bit(I915_WEDGED) to before we complete the inflight requests. When i915_reset() is being blocked on a request, such completion may allow it to start and beginning resetting the GPU before i915_gem_set_wedged() has finished (and so before set-wedge will have marked the device as wedged). As such, i915_gem_init_hw() may see a wedged device even from inside i915_reset().

2018-02-08CRIS: Restore mistakenly cleared kernel MakefileJesper Nilsson
Commit 0fbc0b67a89d7 ("cris: remove arch specific early DT functions") was a bit overzealous in removing the CRIS DT handling, and the complete contents of the Makefile was erased instead of just the line for the devicetree file. This lead to a complete link failure for all SoCs in the CRIS port due to missing symbols. Restore the contents except the line for the devicetree file.

2018-02-08cpufreq: intel_pstate: Enable HWP during system resume on CPU0Chen Yu
When maxcpus=1 is in the kernel command line, the BP is responsible for re-enabling the HWP - because currently only the APs invoke intel_pstate_hwp_enable() during their online process - which might put the system into unstable state after resume. Fix this by enabling the HWP explicitly on BP during resume.

2018-02-08drm/i915: do not stop engines on sanitize if i915.reset=0Daniele Ceraolo Spurio
Since commit 5896a5c8c9c0 (drm/i915: Always stop the rings before a missing GPU reset) we attempt to stop the engines during gem_sanitize even if reset=0 and nothing bad happened on the gpu. The specs says that the STOP_RINGS bit needs to be cleared to resume normal operation, but for some reason the value of the bit seems to be changing without us writing to it (maybe rc6 entry/exit?), so normal operation resumes correctly. However, it still feels incorrect to stop the engines if there hasn't been any issue so skip the whole reset call in gem_sanitize if i915.reset=0 Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180207212440.13438-1-daniele.ceraolospurio@intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
