[M] Change in libosmocore[master]: Avoid reusing pending buffer; append incoming data instead

by jolly

Attention is currently required from: jolly, laforge. Hello Jenkins Builder, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/40584?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Code-Review+1 by laforge, Verified+1 by Jenkins Builder Change subject: Avoid reusing pending buffer; append incoming data instead ...................................................................... Avoid reusing pending buffer; append incoming data instead When reading from a stream, a single read may return only part of a message segment. In such cases, the partial data was stored in 'iofd->pending' and reused for subsequent reads to complete the message. With upcoming changes that submit multiple read SQEs to io_uring, each read uses its own pre-submitted buffer. Reusing 'iofd->pending' is not possible, as the next read buffer is already submitted. This change ensures that newly received data is appended to the existing pending buffer, allowing message segments to accumulate until complete.

[S] Change in libosmocore[master]: Allow io_uring_submit batching just ahead of poll/select

by jolly

Attention is currently required from: jolly, laforge. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/40489?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: Allow io_uring_submit batching just ahead of poll/select ...................................................................... Allow io_uring_submit batching just ahead of poll/select Let's add a mode (enabled via the LIBOSMO_IO_URING_BATCH environment variable), where we don't call io_uring_submit() after every operation we add to the submission queue. Rather, do that once before we go into poll. This should massively reduce the amount of io_uring_enter() syscalls we're seeing.

[M] Change in libosmocore[master]: Automatically increase io_uring, if too small.

by jolly

Attention is currently required from: jolly, pespin. Hello Jenkins Builder, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/40725?usp=email to look at the new patch set (#3). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: Automatically increase io_uring, if too small. ...................................................................... Automatically increase io_uring, if too small. The ring may be too small to store all SQEs before the kernel can handle them. If this happens, a new ring is allocated with twice of the size of the old ring. The old ring will not be destroyed, as it still contains uncompleted elements. Some of them may never be completed. A pointer to the current ring will be stored within the msghdr structure. It is used when cancelling an SQE. The cancellation must be performed in the same ring where it was created. It is quite unlikely that the old ring cannot store the cancellation SQE. If this happens, the kernel is given some time to handle the SQEs. The initial size of the ring can be changed via environment variable.
