2019-06-14docs: kbuild: convert docs to ReST and rename to *.rstMauro Carvalho Chehab
The kbuild documentation clearly shows that the documents there are written at different times: some use markdown, some use their own peculiar logic to split sections. Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

When we have a single image (same firmware image for INIT and OPERATIONAL), we couldn't load the driver and register to the stack if we had hardware RF-Kill asserted. Fix this. This required a few changes: 1) Run the firmware as part of the INIT phase even if its ucode_type is not IWL_UCODE_INIT. 2) Send the commands that are sent to the unified image in INIT flow even in RF-Kill. 3) Don't ask the transport to stop the hardware upon RF-Kill interrupt if the RF-Kill is asserted. 4) Allow the RF-Kill interrupt to take us out of L1A so that the RF-Kill interrupt will be received by the host (to enable the radio).

git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for 5.2 Most likely the last patchset of new feature for 5.2, and this time we have quite a lot of new features. Most obvious being rtw88 from Realtek which supports RTL8822BE and RTL8822CE 802.11ac devices. We have also new hardware support for existing drivers and improvements. There's one conflict in iwlwifi, my example conflict resolution below. Major changes: iwlwifi * bump the 20000-series FW API version * work on new hardware continues * RTT confidence indication support for Fine Timing Measurement (FTM) * an improvement in HE (802.11ax) rate-scaling * add command version parsing from the fimware TLVs * add support for a new WoWLAN patterns firmware API rsi * add support for rs9116 mwifiex * add support for SD8987 brcmfmac * add quirk for ACEPC T8 and T11 mini PCs rt2x00 * add RT3883 support qtnfmac * fix debugfs interface to support multiple cards rtw88 * new driver mt76 * share more code across drivers * add support for MT7615 chipset * rework DMA API * tx/rx performance optimizations * use NAPI for tx cleanup on mt76x02 * AP mode support for USB devices * USB stability fixes * tx power handling fixes for 76x2 * endian fixes Conflicts: There's a trivial conflict in drivers/net/wireless/intel/iwlwifi/fw/file.h, just leave IWL_UCODE_TLV_FW_FSEQ_VERSION to the file.

In the dump info, the driver sets device_family to IWL_FW_ERROR_DUMP_FAMILY_7 in case IWL_FW_ERROR_DUMP_FAMILY_7 is used or IWL_FW_ERROR_DUMP_FAMILY_8 otherwise. This information is misleading and incorrect since the driver sets the device family to 8 to any device that is from family 8 and later, e.g. device family 9 is represented as 8 in the dump. Also, the device family enum is known only to the driver and does not give any information to the FW developer Change the device family to HW type to give propper data about the nic in use.

2019-04-29iwlwifi: mvm: report FTM start time TSF when applicableAvraham Stern
When the interface that is requesting an FTM measurement is connected to a BSS, it is possible that the FTM request was originated by an RRM request from the AP. In this case the station needs to report the measurement start time in terms of the TSF of the AP. Since there is no indication in the FTM request itself if the TSF is needed, always report the TSF if the station is associated.

2019-04-28iwlwifi: mvm: check for length correctness in iwl_mvm_create_skb()Luca Coelho
We don't check for the validity of the lengths in the packet received from the firmware. If the MPDU length received in the rx descriptor is too short to contain the header length and the crypt length together, we may end up trying to copy a negative number of bytes (headlen - hdrlen < 0) which will underflow and cause us to try to copy a huge amount of data. This causes oopses such as this one: BUG: unable to handle kernel paging request at ffff896be2970000 PGD 5e201067 P4D 5e201067 PUD 5e205067 PMD 16110d063 PTE 8000000162970161 Oops: 0003 [#1] PREEMPT SMP NOPTI CPU: 2 PID: 1824 Comm: irq/134-iwlwifi Not tainted 4.19.33-04308-geea41cf4930f #1 Hardware name: [...] RIP: 0010:memcpy_erms+0x6/0x10 Code: 90 90 90 90 eb 1e 0f 1f 00 48 89 f8 48 89 d1 48 c1 e9 03 83 e2 07 f3 48 a5 89 d1 f3 a4 c3 66 0f 1f 44 00 00 48 89 f8 48 89 d1 <f3> a4 c3 0f 1f 80 00 00 00 00 48 89 f8 48 83 fa 20 72 7e 40 38 fe RSP: 0018:ffffa4630196fc60 EFLAGS: 00010287 RAX: ffff896be2924618 RBX: ffff896bc8ecc600 RCX: 00000000fffb4610 RDX: 00000000fffffff8 RSI: ffff896a835e2a38 RDI: ffff896be2970000 RBP: ffffa4630196fd30 R08: ffff896bc8ecc600 R09: ffff896a83597000 R10: ffff896bd6998400 R11: 000000000200407f R12: ffff896a83597050 R13: 00000000fffffff8 R14: 0000000000000010 R15: ffff896a83597038 FS: 0000000000000000(0000) GS:ffff896be8280000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: ffff896be2970000 CR3: 000000005dc12002 CR4: 00000000003606e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: iwl_mvm_rx_mpdu_mq+0xb51/0x121b [iwlmvm] iwl_pcie_rx_handle+0x58c/0xa89 [iwlwifi] iwl_pcie_irq_rx_msix_handler+0xd9/0x12a [iwlwifi] irq_thread_fn+0x24/0x49 irq_thread+0xb0/0x122 kthread+0x138/0x140 ret_from_fork+0x1f/0x40 Fix that by checking the lengths for correctness and trigger a warning to show that we have received wrong data.

2019-04-27netlink: make validation more configurable for future strictnessJohannes Berg
We currently have two levels of strict validation: 1) liberal (default) - undefined (type >= max) & NLA_UNSPEC attributes accepted - attribute length >= expected accepted - garbage at end of message accepted 2) strict (opt-in) - NLA_UNSPEC attributes accepted - attribute length >= expected accepted Split out parsing strictness into four different options: * TRAILING - check that there's no trailing data after parsing attributes (in message or nested) * MAXTYPE - reject attrs > max known type * UNSPEC - reject attributes with NLA_UNSPEC policy entries * STRICT_ATTRS - strictly validate attribute size The default for future things should be *everything*. The current *_strict() is a combination of TRAILING and MAXTYPE, and is renamed to _deprecated_strict(). The current regular parsing has none of this, and is renamed to *_parse_deprecated(). Additionally it allows us to selectively set one of the new flags even on old policies. Notably, the UNSPEC flag could be useful in this case, since it can be arranged (by filling in the policy) to not be an incompatible userspace ABI change, but would then going forward prevent forgetting attribute entries. Similar can apply to the POLICY flag. We end up with the following renames: * nla_parse -> nla_parse_deprecated * nla_parse_strict -> nla_parse_deprecated_strict * nlmsg_parse -> nlmsg_parse_deprecated * nlmsg_parse_strict -> nlmsg_parse_deprecated_strict * nla_parse_nested -> nla_parse_nested_deprecated * nla_validate_nested -> nla_validate_nested_deprecated Using spatch, of course: @@ expression TB, MAX, HEAD, LEN, POL, EXT; @@ -nla_parse(TB, MAX, HEAD, LEN, POL, EXT) +nla_parse_deprecated(TB, MAX, HEAD, LEN, POL, EXT) @@ expression NLH, HDRLEN, TB, MAX, POL, EXT; @@ -nlmsg_parse(NLH, HDRLEN, TB, MAX, POL, EXT) +nlmsg_parse_deprecated(NLH, HDRLEN, TB, MAX, POL, EXT) @@ expression NLH, HDRLEN, TB, MAX, POL, EXT; @@ -nlmsg_parse_strict(NLH, HDRLEN, TB, MAX, POL, EXT) +nlmsg_parse_deprecated_strict(NLH, HDRLEN, TB, MAX, POL, EXT) @@ expression TB, MAX, NLA, POL, EXT; @@ -nla_parse_nested(TB, MAX, NLA, POL, EXT) +nla_parse_nested_deprecated(TB, MAX, NLA, POL, EXT) @@ expression START, MAX, POL, EXT; @@ -nla_validate_nested(START, MAX, POL, EXT) +nla_validate_nested_deprecated(START, MAX, POL, EXT) @@ expression NLH, HDRLEN, MAX, POL, EXT; @@ -nlmsg_validate(NLH, HDRLEN, MAX, POL, EXT) +nlmsg_validate_deprecated(NLH, HDRLEN, MAX, POL, EXT) For this patch, don't actually add the strict, non-renamed versions yet so that it breaks compile if I get it wrong. Also, while at it, make nla_validate and nla_parse go down to a common __nla_validate_parse() function to avoid code duplication. Ultimately, this allows us to have very strict validation for every new caller of nla_parse()/nlmsg_parse() etc as re-introduced in the next patch, while existing things will continue to work as is. In effect then, this adds fully strict validation for any new command. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
