2023-03-07Replace XtRealloc() calls with XtReallocArray()Alan Coopersmith
Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>
2023-03-07Add XtReallocArray() for overflow checking of multiplied argsAlan Coopersmith
Uses reallocarray() if available, otherwise checks for overflow itself, if overflow is possible (i.e. in ILP32 & ILP64 environments, but not LP64 with 32-bit ints). Includes unit tests and XtMallocArray() helper macro. Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>

2022-08-11Use memcpy() instead of XtMemmove() when buffers are known to differAlan Coopersmith
Most of these came from a mass XtBCopy() -> XtMemmove() substitution in 1993 with a commit comment of "ANSIfication". But include/X11/IntrinsicI.h now defines XtMemmmove() as just calling memcpy() as long as src & dst differ, so remove an unnecessary check when we've just allocated a buffer, and reduce the chance that someone thinks we'll actually call memmove() instead of memcpy() Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>

2022-06-20Support buttons > 5 in translation tables [v2]Keith Packard
Add support for arbitrary button numbers by replacing the table-driven detail parsing for BtnDown/ButtonPress and BtnUp/ButtonRelease with a custom parser that allows for an arbitrary button number (1-255) after the 'Button' prefix. Document what this syntax looks like in the table of detail information. Signed-off-by: Keith Packard <keithp@keithp.com>

2021-06-27Fix InternalCallbackRec layout if pointers are bigger than 64 bitsAlex Richardson
When running `xeyes` via `SSH -X` on CHERI-RISC-V FreeBSD, I was getting a Bus Error (unaligned store) in the `cl->callback = callback;` line of _XtAddCallback. The `cl` variable (created using `ToList(icl)`) was only aligned to 8 bytes, but for CHERI-RISC-V pointer-type loads and stores require 16-byte alignment. In order to fix this, I added a C99 flexible array member to internalCallbackRec when compiling for C99 or newer. This ensures that sizeof(InternalCallbackRec) is 16 (since it now includes the required 12 byte padding up to the first XtCallbackRec). This also ensures that alignof(InternalCallbackRec) is 16, but that doesn't matter in this case since malloc() will always return a sufficiently-aligned pointer. I also changed ToList(p) to use the flexible array member directly when compiling for C99. This is not a functional change since it will evaluate to the same pointer, but it does add additional type checking and ensures that only a `InternalCallbackRec *` can be passed to the macro.

2021-06-27Cast via intptr_t when converting integers to pointersAlex Richardson
I found these by compiling libXt with the CHERI Clang compiler, as it warns about conversions from integer to pointer that do not use intptr_t. Signed-off-by: Alex Richardson <Alexander.Richardson@cl.cam.ac.uk>
