Merge topic branch t/spdx into master

Switch to SPDX licence identifiers A single patch which replaces the first comment line of most .c and .h files containing the copyright notice by standardized SPDX (Software/System Package Data Exchange) nomenclature. * t/spdx: Switch to SPDX identifiers.

ipc.c: Drop return value of mutex_destroy().

2026-03-18T21:37:46Z

No caller checks the return value. Log a message on errors rather than fail silently.

Switch to SPDX identifiers.

2026-03-17T22:45:43Z

Generated with sed -i 's|Copyright.*Andre Noll.*|SPDX-License-Identifier: GPL-2.0 */|g' *.c *.h followed by manually tweaking the result a bit. No license change intended.

ipc: Clamp shmmax to 10M.

2025-08-26T14:26:17Z

The old setting may cause OOM on low-memory 32 bit systems.

ipc: Remove pointless initialization in shm_get_shmmax().

2024-05-07T18:28:14Z

The subsequent read() call overwrites the buffer.

Avoid warning about sys/sysctl.h on glibc-2.30.

2019-09-01T11:50:31Z

From glibc-2.30 NEWS: The Linux-specific header and the sysctl function have been deprecated and will be removed from a future version of glibc. Compilation against the glibc-2.30 headers results in the following warning: In file included from ipc.c:10: /usr/include/sys/sysctl.h:21:2: warning: #warning "The header is deprecated and will be removed." [-Wcpp] On NetBSD and FreeBSD, however, we still need to include the header to get the declaration of sysctlbyname(3). This patch changes ipc.c to include sys/sysctl.h only if __FreeBSD__ or __NetBSD__ is defined. Also remove the pointless check for __APPLE__.

Shorten copyright notice.

2017-09-22T14:35:22Z

The GPLv2 line does not add any additional information, so drop it. This leaves a single line of legalese text for most files, which is about the amount of screen real estate it deserves. This patch was created with the following script (plus some manual fixups): awk '{ if (NR <= 5) { gs = gensub(/.*Copyright.* ([0-9]+).*Andre Noll.*/, "\\1", "g") if (gs != $0) year = gs next } if (NR == 6 && year != "") printf("/* Copyright (C) %s Andre Noll , see file COPYING. */\n", year) print }'

doxygen: Add \ref to references.

2017-06-25T18:11:08Z

This way doxygen issues a warning if the file/function/structure no longer exists and a stale reference remains.

load_chunk_table(): Don't trust afhi->chunks_total.

2017-03-25T10:54:36Z

Both callers pass a buffer to load_chunk_table() to initialize afhi->chunk_table. The function does not check the size of the passed buffer but relies on afhi->chunks_total to tell how many values to copy from the buffer. In other words, the buffer size gives an upper bound for the number of chunks in the chunk table, but this bould is not checked. This patch makes the code more robust by adding a suitable check. To this aim, load_chunk_table() is changed to receive a pointer to an osl object (which contains the buffer size) rather than only the buffer. One caller, load_afd(), initializes the chunk table from a shared memory area buffer. It does not know or care about the buffer size so far. We introduce the the new IPC helper shm_size() to let it tell the size of the area and pass it to load_chunk_table().

Update year in copyright headers.

2015-01-12T22:35:45Z

Done with files=$(git grep -l 'Copyright (C) [0-9]\{4\}$-2014$* Andre Noll') sed --in-place= -e 's/Copyright (C) $[0-9]\{4\}$-2014 Andre Noll/Copyright (C) \1 Andre Noll/1' $files In previous years we ran a similar script to set the second year in the range to the current year. This is kind of silly, so let's get rid of this useless information. This commit replaces "Copyright (C) A-B" by "Copyright (C) A" in all file headers, i.e. only the first year (A) is left in. Accurate information including time stamps for each change can be obtained from the git history.
