2024-05-03Tighten boundary check in split(1) to prevent a potential buffer overflow.Shawn Bayern
Before increasing sufflen, make sure the current name plus two (including the terminating NUL character and the to-be-added character) does not exceed the fixed buffer length, and stop immediately if this would occur. In worst case scenario the code would write an nul character beyond the boundary, however it would be caught by open(2) and based on the memory layout, we do not believe this would constitute a security vulnerability.

2023-11-26Remove copyright strings ifdef'd outWarner Losh
We've ifdef'd out the copyright strings for some time now. Go ahead and remove the ifdefs. Plus whatever other detritis was left over from other recent removals. These copyright strings are present in the comments and are largely from CSRG's attempt at adding their copyright to every binary file (which modern interpretations of the license doesn't require).

2023-05-30split(1): add '-c' to continue creating filesJan Schaumann
Currently, split(1) will clobber any existing output files: $ split file; ls xaa xab xac xad $ split second-file; ls xaa xab xac xad xae xaf This patch adds a flag "-c" (mnemonic "create, don't overwrite" or "continue where you left off"): $ split file; ls xaa xab xac xad $ split -c second-file; ls xaa xab xac xad xae xaf xag xah xai xaj Reviewed by: christos Approved by: kevans Different Revision: https://reviews.freebsd.org/D38553
2023-05-30split(1): auto-extend suffix length if requiredJan Schaumann
If the input cannot be split into the number of files resulting from the default suffix length, automatically extend the suffix length rather than bailing out with 'too many files'. Suffixes are extended such that the resulting files continue to sort lexically and "cat *" would reproduce the input. For example, splitting a 1M lines file into (default) 1000 lines per file would yield files named 'xaa', 'xab', ..., 'xyy', 'xyz', 'xzaaa', 'xzaab', ..., 'xzanl'. If '-a' is specified, the suffix length is not auto-extended. This behavior matches GNU sort(1) since around version 8.16.

2022-10-27split: reset errno prior to getline()Math Ieu
Something else may have set errno, breaking the post-getline() logic that tries to detect the getline() error. This was initially noted in a jail on a system that has HPET, in a jail that does not expose /dev/hpet0 -- we see an earlier error in libc's vdso bits. Fixes: 5c053aa3c5e90 ("split: switch to getline() [...]")
2022-10-25split: switch to getline() for line/pattern matchingKyle Evans
Get rid of split's home-grown logic for growing the buffer; arbitrarily breaking at LONG_MAX bytes instead of 65536 bytes gives us much more wiggle room. Additionally, we'll actually fail out entirely if we can't fit a line, which makes noticing this class of problem much easier. Reviewed by: bapt, emaste, pauamma Sponsored by: Klara, Inc.

2017-11-20General further adoption of SPDX licensing ID tags.Pedro F. Giffuni
Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
