2022-08-02ash: fix use-after-free in pattern substituon codeDenys Vlasenko
Patch by soeren@soeren-tempel.net The idx variable points to a value in the stack string (as managed by STPUTC). STPUTC may resize this stack string via realloc(3). If this happens, the idx pointer needs to be updated. Otherwise, dereferencing idx may result in a use-after free. function old new delta subevalvar 1562 1566 +4 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2022-07-03lineedit: get PWD from ashRon Yorston
The line editing code and ash disagree when the current directory is changed to a symbolic link: ~ $ mkdir real ~ $ ln -s real link ~ $ cd link ~/real $ pwd /home/rmyf36/link Note the prompt says we're in ~/real. Bash does: [rmy@random ~]$ cd link [rmy@random link]$ pwd /home/rmyf36/link Ash uses the name supplied by the user while the line editing code calls getcwd(3). The discrepancy can be avoided by fetching the value of PWD from ash. Hush calls getcwd(3) when the directory is changed so there's no disagreement with the line editing code. There is no standard how shells should handle cd'ing into symlinks. function old new delta parse_and_put_prompt 838 869 +31 Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2022-06-26vi: handle autoindent in 'cc' commandRon Yorston
When the 'cc' command is invoked with autoindent enabled it should use the indent of the first line being changed. The size of the indent has to be established before char_insert() is called as the lines being changed are deleted. Introduce a new global variable, newindent, to handle this. The indentcol global is now effectively a static variable in char_insert(). function old new delta do_cmd 4247 4308 +61 vi_main 416 422 +6 char_insert 891 875 -16 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/1 up/down: 67/-16) Total: 51 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2022-06-26vi: fix regression in autoindent handlingRon Yorston
Suppose autoindent is enabled and we have a line with an initial tab where we want to split the words onto separate lines: split the words One way to do this is with the sequence 'f r<CR>;r<CR>', but in BusyBox vi the result is: split he words This is a regression introduced by commit 9659a8db1 (vi: remove autoindent from otherwise empty lines). The amount of indentation is being recorded when the 'r' command inserts a newline but isn't subsequently reset. A fix is to only record the indent when in insert or replace mode. Proper handling of the 'o' and 'O' commands then requires them to switch to insert mode before calling char_insert() to insert a newline. function old new delta char_insert 884 891 +7 do_cmd 4243 4247 +4 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 11/0) Total: 11 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2022-06-26ash,hush: use HOME for tab completion and promptsRon Yorston
ash and hush correctly use the value of HOME for tilde expansion. However the line editing code in libbb obtains the user's home directory by calling getpwuid(). Thus tildes in tab completion and prompts may be interpreted differently than in tilde expansion. When the line editing code is invoked from a shell make it use the shell's interpretation of tilde. This is similar to how GNU readline and bash collaborate. function old new delta get_homedir_or_NULL 29 72 +43 optschanged 119 126 +7 hush_main 1204 1211 +7 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 57/0) Total: 57 bytes v2: Always check for HOME before trying the password database: this is what GNU readline does.

2022-06-26libbb: restore special handling of nomsg errorsRon Yorston
The functions bb_perror_nomsg() and bb_perror_nomsg_and_die() are used to print error messages where no specific information is available. For example: $ busybox mktemp -p / mktemp: (null): Permission denied mktemp(3) doesn't tell us the name of the file it tried to create. However, printing '(null)' is a regression introduced by commit 6937487be (libbb: reduce the overhead of single parameter bb_error_msg() calls). Restore the previous behaviour by reverting the changes to the two functions mentioned: $ busybox mktemp -p / mktemp: Permission denied function old new delta bb_perror_nomsg_and_die 7 14 +7 bb_perror_nomsg 7 14 +7 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 14/0) Total: 14 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

-a meant both "don't up iface before each link detection" and "don't up iface when it newly appears". But they are not the same. I have a dock station where eth1 appears when I attach the notebook to it (looks like it's hanging off a USB bus). IOW: appearance of this interface is functionally equivalent to attaching ethernet cable. ifplugd meant to be able to *automatically* handle this case. Currently, with -a, it couldn't: newly appearing iface stayed down, user had to manually up it. function old new delta packed_usage 34253 34296 +43 .rodata 104876 104877 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 44/0) Total: 44 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
