2024-01-02sed: check errors writing file with sed -iHEADmasterDominique Martinet
sed would currently not error if write failed when modifying a file.

2023-12-31awk: fix handling of empty fieldsDenys Vlasenko
Patch by M Rubon <rubonmtz@gmail.com>: Busybox awk handles references to empty (not provided in the input) fields differently during the first line of input, as compared to subsequent lines. $ (echo a ; echo b) | awk '$2 != 0' #wrong b No field $2 value is provided in the input. When awk references field $2 for the "a" line, it is seen to have a different behaviour than when it is referenced for the "b" line. Problem in BusyBox v1.36.1 embedded in OpenWrt 23.05.0 Same problem also in 21.02 versions of OpenWrt Same problem in BusyBox v1.37.0.git I get the correct expected output from Ubuntu gawk and Debian mawk, and from my fix. will@dev:~$ (echo a ; echo b) | awk '$2 != 0' #correct a b will@dev:~/busybox$ (echo a ; echo b ) | ./busybox awk '$2 != 0' #fixed a b I built and poked into the source code at editors/awk.c The function fsrealloc(int size) is core to allocating, initializing, reallocating, and reinitializing fields, both real input line fields and imaginary fields that the script references but do not exist in the input. When fsrealloc() needs more field space than it has previously allocated, it initializes those new fields differently than how they are later reinitialized for the next input line. This works fine for fields defined in the input, like $1, but does not work the first time when there is no input for that field (e.g. field $99) My one-line fix simply makes the initialization and clrvar() reinitialization use the same value for .type. I am not sure if there are regression tests to run, but I have not done those. I'm not sure if I understand why clrvar() is not setting .type to a default constant value, but in any case I have left that untouched. function old new delta ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/0 up/down: 0/0) Total: 0 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2023-12-13util-linux/lsusb.c: print manufacturer/product strings if availablePeter Korsgaard
Just listing the vendor/product IDs is not always very helpful, so add logic to print the manufacturer and product strings similar to the "big" usbutils versions. Not all devices provide sensible strings though. The usbutils version works around this by falling back to looking up the vendor/product IDs in the hwdb and using those strings instead, which is not an option here - Instead simply trim() the strings for readability. lsusb | sort Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 0bda:5539 Realtek Semiconductor Corp.

2023-10-04udhcp: Avoid leaking uninitialized/stale dataRuss Dill
I noticed a commit in connman: "gdhcp: Avoid leaking stack data via unitiialized variable" [1] Since gdhcp is just BusyBox udhcp with the serial numbers filed off, I checked if BusyBox udhcp has a related issue. The issue is that the get_option logic assumes any data within the memory area of the buffer is "valid". This reduces the complexity of the function at the cost of reading past the end of the actually received data in the case of specially crafted packets. This is not a problem for the udhcp_recv_kernel_packet data path as the entire memory area is zeroed. However, d4/d6_recv_raw_packet does not zero the memory. Note that a related commit [2] is not required as we are zeroing any data that can be read by the get_option function.

2023-08-31ash: initialize basepf.buf in ashzhuyan
When I planned to print the command in read_line_input, I found that after the system started, the command printed for the first time was always garbled. After analysis, it is found that in the init() function of ash, the variable basepf.buf is not initialized after applying for memory, resulting in garbled initial data. Then assign it to the global variable g_parsefile->buf in ash.c, and then pass g_parsefile->buf to the parameter command of the function read_line_input in the function preadfd(), and finally cause it to be garbled when the command is printed by read_line_input. The call stack is as follows: #0 read_line_input (st=0xb6fff220, prompt=0xb6ffc910 "\\[\\033[32m\\]\\h \\w\\[\\033[m\\] \\$ ", command=command@entry=0xb6ffc230 "P\325\377\266P\325\377\266", maxsize=maxsize@entry=1024) at libbb/lineedit.c:2461 #1 0x0043ef8c in preadfd () at shell/ash.c:10812 #2 preadbuffer () at shell/ash.c:10914 #3 pgetc () at shell/ash.c:10997 #4 0x00440c20 in pgetc_eatbnl () at shell/ash.c:11039 #5 0x00440cbc in xxreadtoken () at shell/ash.c:13157 #6 0x00440f40 in readtoken () at shell/ash.c:13268 #7 0x00441234 in list (nlflag=nlflag@entry=1) at shell/ash.c:11782 #8 0x004420e8 in parsecmd (interact=<optimized out>) at shell/ash.c:13344 #9 0x00442c34 in cmdloop (top=top@entry=1) at shell/ash.c:13549 #10 0x00444e4c in ash_main (argc=<optimized out>, argv=0x444e4c <ash_main+1328>) at shell/ash.c:14747 #11 0x00407954 in run_applet_no_and_exit (applet_no=9, name=<optimized out>, argv=0xbefffd34) at libbb/appletlib.c:1024 #12 0x00407b68 in run_applet_and_exit (name=0xbefffe56 "ash", argv=0x9) at libbb/appletlib.c:1047 #13 0x00407f88 in main (argc=<optimized out>, argv=0xbefffd34) at libbb/appletlib.c:1181 Fixes: 82dd14a510ca ("ash: use CONFIG_FEATURE_EDITING_MAX_LEN") Signed-off-by: zhuyan <zhuyan34@huawei.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2023-07-10ash: disable sleep as builtin, closes 15619Denys Vlasenko
Has a few annoying problems: * sleepcmd() -> sleep_main(), the parsing of bad arguments exits the shell. * sleep_for_duration() in sleep_main() has to be interruptible for ^C traps to work, which may be a problem for other users of sleep_for_duration(). * BUT, if sleep_for_duration() is interruptible, then SIGCHLD interrupts it as well (try "/bin/sleep 1 & sleep 10"). * sleep_main() must not allocate anything as ^C in ash longjmp's. (currently, allocations are only on error paths, in message printing). Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
