This is on an Rpi B3+ runint aarch64. I have noticed that, periodically I get disconnected and it doe snot reconnect. I am using connman to manage the iwd connection. This is the first time I have seen the crash in the log. It has been crashing and not recovering. It gets a Deauth event (I've seen this quite a bit) and usually, it will not reconnect until I reboot it and my router. How can I best diagnose this? It is iwd 1.7 and connman 1.38. potentially useful excerpts from my journal: Jun 17 23:26:58 rune64 kernel: Booting Linux on physical CPU 0x0000000000 [0x410fd034] Jun 17 23:26:58 rune64 kernel: Linux version 5.4.44-1-ARCH (alarm@buildrune64) (gcc version 9.3.0 (GCC)) #1 SMP PREEMPT Mon Jun 22 15:13:50 CDT 2020 Jun 17 23:26:58 rune64 kernel: Machine model: Raspberry Pi 3 Model B Plus Rev 1.3 ...

[PATCH v2 0/7] Radio Management Module

by James Prestwood

Version 2: - Renamed from 'offchannel' - Fixed potential problems in initial p2p patch. Added work ID tracking as well as setting ID to zero once completed since the ID is reused for multiple requests. If Andrew could verify everything looks ok that would be great. - Changed priority from enum to integer. This makes things much more flexible. - Removed the concept of suspended completely. This was to support scanning but with the addition of priorities we can actually insert ANQP entries before any pending scans, which avoids needing to suspend scanning. - Connection attempts are now treated as radio management work items. This in addition to the above changes allow us again to avoid suspending scans as well as waiting for ANQP to complete before connecting. Connections can be inserted after ANQP, but before scans which removes the need for the ANQP watch in station. James Prestwood (7): radio_mgmt: introduce new radio management module wiphy: integrate radio management module frame-xchg: refactor to use radio management module anqp: refactor to use frame-xchg scan: refactor to use radio management module network: use radio management for connections station: remove ANQP watch Makefile.am | 1 + src/anqp.c | 443 ++++++++++------------------------------------- src/anqp.h | 3 +- src/frame-xchg.c | 99 +++++------ src/frame-xchg.h | 6 +- src/network.c | 148 ++++++++-------- src/p2p.c | 22 ++- src/radio_mgmt.c | 240 +++++++++++++++++++++++++ src/radio_mgmt.h | 48 +++++ src/scan.c | 104 ++++------- src/scan.h | 3 - src/station.c | 75 ++------ src/station.h | 5 - src/wiphy.c | 5 + 14 files changed, 575 insertions(+), 627 deletions(-) create mode 100644 src/radio_mgmt.c create mode 100644 src/radio_mgmt.h -- 2.21.1

iwd 1.8 causes kernel oops

by caljorden＠hotmail.com

Hi all, I have observed on my two main machines that I am getting a kernel oops when I boot that only occurs when I am running IWD 1.8. When I downgrade to IWD 1.7, the oops goes away. I have observed this on kernels 5.7.4 and 5.7.5 (at least). The kernel oops does not seem to negatively impact the operation of the system, and wireless works fine after this as well. Here are the oops details: [ 2.951230] ------------[ cut here ]------------ [ 2.951235] WARNING: CPU: 13 PID: 3703 at net/wireless/nl80211.c:7259 nl80211_get_reg_do+0x1f1/0x220 [ 2.951235] Modules linked in: algif_aead algif_skcipher md4 algif_hash af_alg amd64_edac_mod(-) pcc_cpufreq(-) iwlmvm btusb btrtl btbcm btintel bluetooth ecdh_generic iwlwifi ecc snd_hda_codec_realtek snd_hda_codec_generic snd_hda_codec_hdmi crc32_pclmul crc32c_intel ghash_clmulni_intel aesni_intel crypto_simd cryptd snd_hda_intel glue_helper snd_intel_dspcfg snd_hda_codec k10temp snd_hwdep snd_hda_core [ 2.951245] CPU: 13 PID: 3703 Comm: iwd Tainted: G T 5.7.5 #2 [ 2.951246] Hardware name: Micro-Star International Co., Ltd.

I tried to strace it, and it seems to be having some issue with accessing the kernel keystore, maybe?) I wanted to report this here so that it would be noticed, and possibly fixed in a future release. I am happy to test patches.

Re: Fw: Failed to load trusted user certificate

Right, we've seen this feature request somewhere recently and thought that it may be easy to support this format in IWD. Do you happen to know where this format is specified? Best regards

[PATCH v2] test-runner: use WNOHANG option waiting for PID

by James Prestwood

If an application has a bug and hangs on SIGTERM this causes test-runner to hang as well. This is obviously an issue with the application in question, but test-runner should have a way of continuing onto the next test rather than hanging. Instead we can use WNOHANG and a sleep to allow applications some amount of time to exit, and if they haven't use SIGKILL instead as well as print an error. Similar to how wait_for_socket works. The timeout is hard coded to 2 seconds (100ms sleep + 20 iterations). --- tools/test-runner.c | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) v2: - Removed extra check for i >= 20 since that is always going to be true if we get past the while loop - Added another waitpid after SIGKILL diff --git a/tools/test-runner.c b/tools/test-runner.c index f8677be5..83d5194d 100644 --- a/tools/test-runner.c +++ b/tools/test-runner.c @@ -626,14 +626,24 @@ exit: static void kill_process(pid_t pid) { int status; + int i = 0; l_debug("Terminate pid: %d", pid); kill(pid, SIGTERM); do { - waitpid(pid, &status, 0); - } while (!WIFEXITED(status) && !WIFSIGNALED(status)); + if (waitpid(pid, &status, WNOHANG) == pid) + return; + + usleep(100000); + } while (!WIFEXITED(status) && !WIFSIGNALED(status) && i++ < 20); + + l_error("Failed to kill process %d gracefully", pid); + kill(pid, SIGKILL); + + /* SIGKILL shouldn't need WNOHANG */ + waitpid(pid, &status, 0); } static bool wait_for_socket(const char *socket, useconds_t wait_time) -- 2.21.1

[PATCH] frame-xchg: fix incorrect length check

by James Prestwood

frame_xchg_startv was using sizeof(mmpdu) to check the minimum length for a frame. Instead mmpdu_header_len should be used since this checks fc.order and returns either 24 or 28 bytes, not 28 bytes always. This change adds the requirement that the first iovec in the array must contain at least the first 2 bytes (mmpdu_fc) of the header. This really shouldn't be a problem since all current users of frame-xchg put the entire header (or entire frame) into the first iovec in the array. --- src/frame-xchg.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/src/frame-xchg.c b/src/frame-xchg.c index dd60e080..3744a4c1 100644 --- a/src/frame-xchg.c +++ b/src/frame-xchg.c @@ -1090,12 +1090,17 @@ uint32_t frame_xchg_startv(uint64_t wdev_id, struct iovec *frame, uint32_t freq, size_t frame_len; struct iovec *iov; uint8_t *ptr; - struct mmpdu_header *mpdu; for (frame_len = 0, iov = frame; iov->iov_base; iov++) frame_len += iov->iov_len; - if (frame_len < sizeof(*mpdu)) { + /* + * This assumes that the first iovec at least contains the mmpdu_fc + * portion of the header used to calculate the minimum length. + */ + if (frame[0].iov_len >= 2 && frame_len < + mmpdu_header_len((const struct mmpdu_header *) + frame[0].iov_base)) { l_error("Frame too short"); cb(-EMSGSIZE, user_data); return 0; -- 2.21.1
