* ash: make EPOCH variables work if RANDOM is disabledRon Yorston2023-03-291-1/+1
| | | | | | | | | | | | | | | Commit 1d37186fe2 (ash: add bash-compatible EPOCH variables) added support for the EPOCHSECONDS and EPOCHREALTIME variables. These variables are dynamic and therefore require the VDYNAMIC flag to be non-zero. However, this is only the case if support for the RANDOM variable is enabled. Give VDYNAMIC a non-zero value if either EPOCH variables or RANDOM are enabled. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* lineedit: fix matching of directories when searching PATHRon Yorston2023-03-291-2/+2
| | | | | | | | | | | | | | | Commit 8baa643a3 (lineedit: match local directories when searching PATH) included subdirectories of the current directory in the search when tab-completing commands. Unfortunately a short time later commit 1d180cd74 (lineedit: use strncmp instead of is_prefixed_with (we know the length)) broke this feature by returning an incorrect length for the array of paths. Fix the length and reinstate matching of subdirectories. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Modify the timestamp conversion to shift values between 1900-1970 (in the first era) to the second era to enable the client to measure its offset correctly until year 2106 (assuming 64-bit time_t). Also update the conversion from double used when stepping the clock to work with 64-bit time_t after reaching the maximum 32-bit value in 2038 and the server conversion to work correctly in the next NTP era. function old new delta lfp_to_d 51 64 +13 step_time 326 332 +6 .rodata 105260 105264 +4 d_to_lfp 100 86 -14 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/1 up/down: 23/-14) Total: 9 bytes Signed-off-by: Miroslav Lichvar <mlichvar@redhat.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
* ed: don't use memcpy with overlapping memory regionsSören Tempel2023-01-051-1/+1
| | | | | | | | | | | | | | | | | | The memcpy invocations in the subCommand function, modified by this commit, previously used memcpy with overlapping memory regions. This is undefined behavior. On Alpine Linux, it causes BusyBox ed to crash since we compile BusyBox with -D_FORTIFY_SOURCE=2 and our fortify-headers implementation catches this source of undefined behavior [0]. The issue can only be triggered if the replacement string is the same size or shorter than the old string. Looking at the code, it seems to me that a memmove(3) is what was actually intended here, this commit modifies the code accordingly.
