2023-12-23Update to perl 5.36.3Andrew Fresh
No changes to perl, as those were already committed for the earlier errata. This just brings documentation and such in line with upstream. ok bluhm@
2023-12-13OSF/1 placed alpha binaries above 4G. This affects our nopie binaries,Theo de Raadt
of which there is only one -- instbin, on the install media. But that is incompatible with the 32-bit offsets in openbsd.syscalls. Move the start of openbsd nopie binaries much lower. ok kettenis

2023-11-26Add arm64 bti pads for range extension thunks.Tobias Heider
Large arm64 binaries like chromium use range extension thunks for accessing plt entries. Add bti landing pads for the additional indirection. upstream commit: 60827df765156cee6cca3dc5049388dde9dac1c0 ok kettenis@
2023-11-26Fix read/write past buffer endAndrew Fresh
From upstream commit: From 7047915eef37fccd93e7cd985c29fe6be54650b6 Mon Sep 17 00:00:00 2001 From: Karl Williamson <khw@cpan.org> Date: Sat, 9 Sep 2023 11:59:09 -0600 Subject: [PATCH] Fix read/write past buffer end: perl-security#140 A package name may be specified in a \p{...} regular expression construct. If unspecified, "utf8::" is assumed, which is the package all official Unicode properties are in. By specifying a different package, one can create a user-defined property with the same unqualified name as a Unicode one. Such a property is defined by a sub whose name begins with "Is" or "In", and if the sub wishes to refer to an official Unicode property, it must explicitly specify the "utf8::". S_parse_uniprop_string() is used to parse the interior of both \p{} and the user-defined sub lines. In S_parse_uniprop_string(), it parses the input "name" parameter, creating a modified copy, "lookup_name", malloc'ed with the same size as "name". The modifications are essentially to create a canonicalized version of the input, with such things as extraneous white-space stripped off. I found it convenient to strip off the package specifier "utf8::". To to so, the code simply pretends "lookup_name" begins just after the "utf8::", and adjusts various other values to compensate. However, it missed the adjustment of one required one. This is only a problem when the property name begins with "perl" and isn't "perlspace" nor "perlword". All such ones are undocumented internal properties. What happens in this case is that the input is reparsed with slightly different rules in effect as to what is legal versus illegal. The problem is that "lookup_name" no longer is pointing to its initial value, but "name" is. Thus the space allocated for filling "lookup_name" is now shorter than "name", and as this shortened "lookup_name" is filled by copying suitable portions of "name", the write can be to unallocated space. The solution is to skip the "utf8::" when reparsing "name". Then both "lookup_name" and "name" are effectively shortened by the same amount, and there is no going off the end. This commit also does white-space adjustment so that things align vertically for readability.

image, in addition to or instead of the x86 boot image, to the output file. Per the UEFI standard, the EFI boot image should be an image of an EFI System Partition to be loaded in no-emulation mode, so we always record it that way rather than checking if it looks like a floppy image. with, tested by and ok yasuoka@ strong encouragement from deraadt@
2023-11-20Stop erroring out when .gcc_except_table relocs point at discarded sectionsJeremie Courreges-Anglas
lang/gcc on riscv64 has a wart, it creates such relocs which upset ld.lld. The workaround I have used in lang/gcc since Sep 2022 doesn't work any more, so ask ld.lld to be more lenient. This will let the fortran ports and friends build on riscv64. clang has fixed since some time already, but our lang/gcc port will likely keep that wart for some time.

2023-11-19Fix cc -ftrapping-math on macppcGeorge Koehler
Handle CALL_RM like CALL for 32-bit ELF. If a function call has the strictfp attribute, its opcode changes from CALL to CALL_RM. If a call uses the secure PLT, then it must getGlobalBaseReg() to set r30. After I rebuilt xenocara/lib/pixman with this change, Xorg stopped crashing on my macppc. pixman uses cc -ftrapping-math which puts strictfp on each function call. https://github.com/llvm/llvm-project/pull/72758 ok jca@ tobhe@ deraadt@

in a hash instead. Side effect: we no longer parse the same tc again and again, leading to a smaller result with the same capabilities but no duplicates. (instead of parsing 36 entries for xterm, we end up with 10 entries, as the "tc=" stuff is actually a tree instead of a list: xterm references several intermediate tc that all lead to the same basic list !)
