* Double the size of ARG_MAX on LP64 platforms.Pedro F. Giffuni2019-12-161-1/+5
| | | | | | | | | | | | | | | | | | | | | | | As modern software keeps growing in size, we get requests to update the value of ARG_MAX in order to link the resulting object files. Other OSs have much higher values but Increasiong ARG_MAX has a multiplied effect on KVA, so just bumping this value is dangerous in some archs like ARM32 that can exhaust KVA rather easily. While it would be better to have a unique value for all archs, other OSs (Illumos in partidular) can have different ARG_MAX limits depending on the platform, For now we want to be really conservative so we are avoidng the change on ILP32 and in the alternative case we only double it since that seems to work well enough for recent Code Aster. I was planning to bump the _FreeBSD_version but it was bumped recently (r355798) so we can reuse the 1300068 value for this change.

* Remove LINK_MAX.John Baldwin2018-01-051-1/+0
| | | | | | | | | | | | | | | After recent changes to change filesystems to use filesystem-specific limits, LINK_MAX is no longer used in the base system. Applications should in theory be able to cope with a lack of LINK_MAX by using pathconf().

* sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | 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=326023
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Rework the credential code to support larger values of NGROUPS andBrooks Davis2009-06-191-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NGROUPS_MAX, eliminate ABI dependencies on them, and raise the to 1024 and 1023 respectively. (Previously they were equal, but under a close reading of POSIX, NGROUPS_MAX was defined to be too large by 1 since it is the number of supplemental groups, not total number of groups.) The bulk of the change consists of converting the struct ucred member cr_groups from a static array to a pointer. Do the equivalent in kinfo_proc. Introduce new interfaces crcopysafe() and crsetgroups() for duplicating a process credential before modifying it and for setting group lists respectively. Both interfaces take care for the details of allocating groups array. crsetgroups() takes care of truncating the group list to the current maximum (NGROUPS) if necessary. In the future, crsetgroups() may be responsible for insuring invariants such as sorting the supplemental groups to allow groupmember() to be implemented as a binary search. Because we can not change struct xucred without breaking application ABIs, we leave it alone and introduce a new XU_NGROUPS value which is always 16 and is to be used or NGRPS as appropriate for things such as NFS which need to use no more than 16 groups. When feasible, truncate the group list rather than generating an error. Minor changes: - Reduce the number of hand rolled versions of groupmember(). - Do not assign to both cr_gid and cr_groups[0]. - Modify ipfw to cache ucreds instead of part of their contents since they are immutable once referenced by more than one entity.

| | | | | | | | | | | arm and powerpc have 64KB as the maximum argument size, so one cannot run "make delete-old" on arm or powerpc anymore. Stop special-casing powerpc and give it 256KB of arguments like all other platforms, but keep arm on 64KB for now. There may be a purpose to it that doesn't exist for powerpc.

* netchild's mega-patch to isolate compiler dependencies into a centralJoerg Wunsch2005-03-021-1/+4
| | | | | | | | | | | | | | | | | | | place. This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42. By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.
