It seems that alsa-project.org mailman re-sends the post with xxx(a)alsa-project.org address sometimes, indeed. I don't know the condition, but now I noticed it while checking the pending approvals. Those that appeared in the list wrongly were likely the posts I approved without knowing them being superfluously resent ones.

Last time this topic was raised (on infradead), I talked to someone from Gmail. The ask was that originating servers implement DKIM signing, and intermediate servers, i.e. mailing lists, not mangle the signed fields. The latter includes not adding footers, and not re-emitting headers, which may alter the amount of whitespace, based on some of my experiments. ChenYu

I checked infradead and they're using mailman 2. Mailman 2 does not support DMARC mitigation. > I believe vger does sometimes manage some backchannel which probably > helps it somewhat. Using a non-standard mechanism is not a big win. DMARC is a internet standard - see RFC7489, RFC8616. It means that the mailing lists cannot send e-mails with From from other domains which have restricted policies set by *their* administrators. So basically, all mail servers violates this if they keep the From header. Mailman 3 implemented several types of mitigations and the message wrap is the best one in my eyes. The mangling of the From header or reject e-mails from those senders is even worse (see [1]). When I turn off the mitigation in mailman, my ALSA server will have bad reputation for gmail users soon in an unpredictable manner. I also saw that ATT incoming mail servers had similar issues. We can expect that the list of the ingress SMTP servers not accepting e-mails based on the DMARC policy will grow. It's something that we don't have under control. If we don't find that it's time to move forward and accept this policy, I can turn off the mitigation, but in a cost that gmail (and soon maybe other) users will bomb me (they already did last years) that the ALSA mail server does not deliver e-mails for them. Are we a community on internet or not? Ideally, we should start upgrade and fix our tools... Let me just know, if you (and Takashi) insist to turn the mitigation off after this discussion.

Hi Mark, sorry to hear that. The fact mailman is disrupting your workflow as ASoC maintainer is alarming, and I hope you and Jaroslav can work out a solution. But besides my suggestion that the added headers in the body of the message *start* with at least the correct "From:" field, I can't be of much help. Thanks for the hard work, Geraldo Nascimento

Try applying the patches with git am... Mark, I think Jaroslav can change the behaviour in the the added Headers in the body of the message (the added Headers in the body have e.g. the correct From: email information). If the message body *starts* with the "From:", "Subject:" and "Date:" fields I think git-am will pickup the correct information from the body instead of from the mangled headers. Hopefully... Good luck, Geraldo Nascimento

Hi Mark, Are you complaining about the added headers in the message? Because the patch itself didn't look mangled from my side. From my understanding, Jaroslav had to start mangling mail addresses due to strict DMARC rules which make some servers reject the message from alsa-devel. Thanks, Geraldo Nascimento > > Thanks, > Mark

Bad magic error when loading SOF firmware
by David Sayada 04 May '23

04 May '23

Hello SOF team, We are trying to evaluate the SOF project on our 8MPLUSSLPD4-EVK based product, and we are getting some issues when trying to run one of the "yocto compiled" SOF Firmware. Below is the procedure we are trying to perform: *echo /lib/firmware/imx/sof/sof-imx8m.ri > /sys/class/remoteproc/remoteproc0/firmware* *echo start > /sys/class/remoteproc/remoteproc0/state* We are getting, at the end, a "Image is corrupted (bad magic)" -22 return code. We have also created a VM (based on SOF 2.4.1) where we can compile (and sign, with default keys) the different toolchains and firmwares. Will that help in having a firmware run correctly? Maybe, we are doing incorrect things, if this is the case, please advise. Best regards, David Sayada.

[PATCH] ASoC: SOF: Intel: hda-stream: Move three variable assignments behind condition checks in hda_dsp_iccmax_stream_hw_params()
by Markus Elfring 24 Apr '23

24 Apr '23

Date: Wed, 19 Apr 2023 20:42:19 +0200 The address of a data structure member was determined before a corresponding null pointer check in the implementation of the function “hda_dsp_iccmax_stream_hw_params”. Thus avoid the risk for undefined behaviour by moving the assignment for three local variables behind some condition checks. This issue was detected by using the Coccinelle software.
