2025-07-04shell: empty HISTFILE disables history saving, just as unset one didDenys Vlasenko3-4/+6
The rationale here is that unsetting HISTFILE in /etc/profile does not "stick": if it's unset, the default one is set later (after /etc/profile is executed) by the shell. But setting (and exporting, so it is inherited by all (grand)child shells) an empty one works. function old new delta save_history 296 316 +20 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

"HISTFILESIZE=0" in profile wasn't working as intended, "unset HISTFILE" wasn't preventing creation of history files Now: HISTSIZE=n allows to reduce in-memory history buffer HISTFILESIZE=n allows to reduce history file size (0: truncate it) unset HISTFILE allows to not save history file at all function old new delta exitshell 138 194 +56 hush_exit 97 143 +46 save_history 266 296 +30 hush_main 1170 1186 +16 .rodata 105762 105771 +9 load_history 246 254 +8 size_from_HISTFILESIZE 44 41 -3 read_line_input 2746 2712 -34 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 6/2 up/down: 165/-37) Total: 128 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2025-07-01libbb: Prevent clang from reading the G pointer before it is assignedBin Meng2-20/+23
It was observed that getty crashes on RISC-V 64-bit target, with the busybox binary compiled by clang/LLVM 17 with -O2. Not only getty, but also some other applets like syslogd/vi are broken too. Commit 5156b245 ("Make const ptr assign as function call in clang") introduced XZALLOC_CONST_PTR() to defeat the compiler optimization, however it only fixed a small number of broken places when compiling busybox with clang/LLVM. A large number of places remain broken. This commit treats ASSIGN_CONST_PTR() the same way as XZALLOC_CONST_PTR().

2025-07-01shell: improve bash compatibility of read built-inRon Yorston11-33/+63
Make the read built-in more compatible with bash: - Return an exit code of 142 on timeout. - When the timeout expires before a newline is detected in the input bash captures the partial input. This behaviour is new since bash version 4.4. BusyBox shells had the pre-4.4 behaviour where the input was lost. Update the tests to suit and fix a couple of compiler errors in the testsuite. function old new delta builtin_read 154 174 +20 readcmd 213 228 +15 shell_builtin_read 1364 1370 +6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 41/0) Total: 41 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

setup_unzip_on_fd() does not return the transformer structure, so the user does not know how much to seek back (or alternatively what the signature was) when compressor signature is not detected. Currently not needed (the only user is tar which dies anyway).

2025-04-08syslogd: Fix 'OPT_locallog' check regression in 'syslogd_main'Grant Erickson1-1/+1
In the recent refactoring of 'syslogd_main', a regression was introduced in handling the manual bitwise OR of 'OPT_locallog' as follows: if (ENABLE_FEATURE_REMOTE_LOG && !(opts & OPT_remotelog)) // -R option_mask32 |= OPT_locallog; 'opts' represents the locally-scoped output of 'getopt32' and 'option_mask32' represents the globally-scoped state of the same. Consequently, the above performs a bitwise OR to include 'OPT_locallog' of the globally-scoped option state, which 'opts' will not reflect locally. Manipulating the global, rather than local, state is correct as 'timestamp_and_log_internal' will later need to check 'OPT_locallog'. However, when the aforementioned refactor occurred, the following regressing change was made: - if (!ENABLE_FEATURE_REMOTE_LOG || (option_mask32 & OPT_locallog)) { + if (!ENABLE_FEATURE_REMOTE_LOG || (opts & OPT_locallog)) { breaking the spatially- and temporally-removed check in 'timestamp_and_log_internal'.

2025-02-09udhcpc6: generate a consistent IAIDZhou Siqi1-2/+27
Currently, udhcpc6 does not meet the requirements for Identity Association in RFC 3315. This is a specific explanation in RFC 3315 protocol: https://datatracker.ietf.org/doc/html/rfc3315#section-10 "The IAID uniquely identifies the IA and must be chosen to be unique among the IAIDs on the client. The IAID is chosen by the client. For any given use of an IA by the client, the IAID for that IA MUST be consistent across restarts of the DHCP client." This patch makes the client generate a consistent IAID based on the MAC address. function old new delta send_d6_discover 285 270 -15 Signed-off-by: Zhou Siqi <zhousiqi5@huawei.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

Several small improvements to udhcpc6. - Remove usage text for the nonexistent -B option. - Fix a segfault when renewing an IA_PD lease without IA_NA (which means the client hasn't been assigned an ip, so we cannot locally bind to it). - Fix NAK management: check the option length, and print the status code and status message - Add a -m option to always send renew requests as multicast. These last two changes are useful to deal with hopelessly broken DHCPv6 servers such as the one from the Orange Livebox (one of the main French ISPs) which I'm currently having the displeasure to have to talk to, hence the patch. function old new delta static.send_d6_renew - 126 +126 .rodata 105598 105649 +51 udhcpc6_main 2607 2650 +43 packed_usage 34933 34953 +20 d6_send_kernel_packet_from_client_data_ifindex 266 282 +16 send_d6_renew 174 - -174 ------------------------------------------------------------------------------ (add/remove: 1/1 grow/shrink: 4/0 up/down: 256/-174) Total: 82 bytes Signed-off-by: Laurent Bercot <ska-dietlibc@skarnet.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
