rt2x00 uses the deprecated do_gettimeofday() function to get a timestamp for its debugfs "dump" file interface. The timestamp is using an unsigned 32-bit value, so we could make it work until 2106 by using ktime_get_real_ts64(), but it seems better to use monotonic times, as we normally want for timestamps. Since this is an interface change, I'm incrementing the DUMP_HEADER_VERSION number, so user space can figure out whether the timestamps are monotonic or not. Most likely the tools won't care either way. Generally speaking, ABI version numbers and in particular changing them is a bad idea. However since this is in debugfs, we don't put any API stability rules on the interface according to Documentation/filesystems/debugfs.txt, and we can take the easy way out here; anyone using the frame dump feature can probably work out the differences here.

ENOENT usb error mean "specified interface or endpoint does not exist or is not enabled". Mark device not present when we encounter this error similar like we do with ENODEV error. Otherwise we can have infinite loop in rt2x00usb_work_rxdone(), because we remove and put again RX entries to the queue infinitely. We can have similar situation when submit urb will fail all the time with other error, so we need consider to limit number of entries processed by rxdone work. But for now, since the patch fixes reproducible soft lockup issue on single processor systems and taken ENOENT error meaning, let apply this fix. Patch adds additional ENOENT check not only in rx kick routine, but also on other places where we check for ENODEV error. Reported-by:

Specifically, following parameters are needed for wireless device configuration but were not available to it before: - HT/VHT capabilities and capabilities masks. - full channel info (not just IEEE number) - BSSID hint - previous BSSID for reassoc request Move Management Frame Protection setting from common encr info structure into STA-specific .connect command parameters. Make sure that all new qlink structure definitions are alignment-safe. Signed-off-by:

Current logic artificially divides "start AP" procedure into three stages: - generic interface configuration (security, channel etc) - IE's processing - enable AP mode on interface This separation would not allow to do a proper device configuration as first stage needs to use information from IEs that are processed on a second stage. Which means first and second stages have to be meged. In that case there is no point anymore to keep third stage either, so merge all three into a single command. This new command carries all the same info as contained in "struct cfg80211_ap_settings". Signed-off-by:

Information on which HT/VHT capabilities can be overridden is reported per-MAC by wireless device. Signed-off-by:
-
Igor Mitsyanko authored
HT/VHT capabilities must be reported per each band supported by a radio, not for all bands on a radio. Furthermore, driver better not assume any capabilities and just use whetever is reported by device itself. To support this, convert "get channels" command into "get band info" command. Difference is that it may also carry HT/VHT capabilities along with channels information. While at it, also add "num_bitrates" field to "get band info" command, for future use. Signed-off-by:

The firmware uses a mailbox to communicate to the host what is going on. In the driver we validate the bit received. Various people seen the following message: brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012 Bit 4 is cause of this message, but this actually indicates the firmware has halted. Handle this bit by giving a more meaningful error message. Reviewed-by:

do_gettimeofday() is deprecated and slower than necessary for the purpose of reading the seconds. This changes rtl_op_suspend/resume to use ktime_get_real_seconds() instead, which is simpler and avoids confusion about whether it is y2038-safe or not. Signed-off-by:

We set rtlhal->last_suspend_sec to an uninitialized stack variable, but unfortunately gcc never warned about this, I only found it while working on another patch. I opened a gcc bug for this. Presumably the value of rtlhal->last_suspend_sec is not all that important, but it does get used, so we probably want the patch backported to stable kernels.

Roman Gushchin says: ==================== eBPF-based device cgroup controller This patchset introduces an eBPF-based device controller for cgroup v2. Patches (1) and (2) are a preparational work required to share some code with the existing device controller implementation. Patch (3) is the main patch, which introduces a new bpf prog type and all necessary infrastructure. Patch (4) moves cgroup_helpers.c/h to use them by patch (4). Patch (5) implements an example of eBPF program which controls access to device files and corresponding userspace test. v3: Renamed constants introduced by patch (3) to BPF_DEVCG_* v2: Added patch (1). v1: https://lkml.org/lkml/2017/11/1/363 ==================== Signed-off-by:

Add a test for device cgroup controller. The test loads a simple bpf program which logs all device access attempts using trace_printk() and forbids all operations except operations with /dev/zero and /dev/urandom. Then the test creates and joins a test cgroup, and attaches the bpf program to it. Then it tries to perform some simple device operations and checks the result: create /dev/null (should fail) create /dev/zero (should pass) copy data from /dev/urandom to /dev/zero (should pass) copy data from /dev/urandom to /dev/full (should fail) copy data from /dev/random to /dev/zero (should fail) Signed-off-by:

Cgroup v2 lacks the device controller, provided by cgroup v1. This patch adds a new eBPF program type, which in combination of previously added ability to attach multiple eBPF programs to a cgroup, will provide a similar functionality, but with some additional flexibility. This patch introduces a BPF_PROG_TYPE_CGROUP_DEVICE program type. A program takes major and minor device numbers, device type (block/character) and access type (mknod/read/write) as parameters and returns an integer which defines if the operation should be allowed or terminated with -EPERM.

This is non-functional change to prepare the device cgroup code for adding eBPF-based controller for cgroups v2. The patch performs the following changes: 1) __devcgroup_inode_permission() and devcgroup_inode_mknod() are moving to the device-cgroup.h and converting into static inline. 2) __devcgroup_check_permission() is exported. 3) devcgroup_check_permission() wrapper is introduced to be used by both existing and new bpf-based implementations.
