| * examples/udhcp/simple.script: fix IPv6 support when using udhcpcStefan Agner2020-06-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The udhcpc script calls ip addr flush .. which flushes addresses of any address family, including IPv6. However, busybox udhcpc is IPv4 only and should not influence IPv6 addressing. Hence use ip addr flush with family constraint. The script particularly broke IPv6 SLAAC: Typically when udhcpc calls the script the kernel already assigned the IPv6 link-local address. The flush removes the link-local IPv6 address again and prohibits proper IPv6 operation such as SLAAC since neighbor discovery protocol relies on IPv6 link-local addressing.

| * deluser: check if specified home is a directory before removing itSören Tempel2020-06-091-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Alpine, some users use /dev/null as a home directory. When removing such a user with `deluser --remove-home` this causes the /dev/null device file to be removed which is undesirable. To prevent this pitfall, check if the home directory specified for the user is an actual directory (or a symlink to a directory). Implementations of similar tools for other operating systems also implement such checks. For instance, the OpenBSD rmuser(1) implementation [0].

| * httpd: allow '-h' to work when daemonized with NOMMU enabledRon Yorston2020-06-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d1b75e184 (httpd: permit non-default home directory with NOMMU enabled) only works when used with the '-f' (foreground) option. When '-f' isn't specified and NOMMU is enabled bb_daemonize_or_rexec() is called to daemonize the server. Since the server process has been re-execed the previous patch results in the xchdir() not being called. Fix this by resetting the re_execed variable in this case.

* | chattr, lsattr: enable in the default configurationRon Yorston2020-07-096-7/+138
| | | | | | | | | | | | | | | | | | | | The chattr and lsattr utilities allow file attributes to be changed and displayed. Modify them to support Windows file attributes using the same names as Cygwin. Only allow a limited subset of attributes to be changed: just most of those supported by SetFileAttributes(). Since it isn't possible to set all attributes the '=' operator isn't allowed.
* | ls: treat hidden files as if their names begin with a dotRon Yorston2020-07-091-0/+12
| | | | | | | | | | | | | | On Unix 'ls' treats filenames starting with a dot as hidden and only displays them if the '-a' or '-A' option is given. Extend similar treatment to files with the Windows hidden flag.
* | win32: return raw file attributes in struct mingw_statRon Yorston2020-07-092-0/+5
| | | | | | | | | | | | Until now the emulated stat(2) system calls have only returned a synthesised Unix-style mode value. Also return the raw Windows file attributes.
* | ash: fix shell optionsRon Yorston2020-07-071-7/+7
| | | | | | | | | | | | The Windows-specific shell options winxp, noconsole and nocaseglob have had the wrong indices in optlist since the merge with upstream BusyBox in commit 517cf74f6.
* | ash: improve handling of UNC pathsRon Yorston2020-06-302-38/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Be more strict about identifying UNC paths in unc_root_len(). In updatepwd() in ash: - Skip duplicate leading slashes unless the directory is a UNC path. - Rewrite detection and handling of the five possible types of path. This improves cases like 'cd ///' and 'cd /xyz' when the current directory is a UNC path. See GitHub issue #192.
* | ash: avoid duplicated slashes in output of type/command builtinsRon Yorston2020-06-292-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Microsoft developers have a penchant for adding trailing slashes to entries in PATH: C:/Windows/System32/WindowsPowerShell/v1.0/ C:/Windows/System32/OpenSSH/ The 'type' and 'command -v' shell builtins return paths with duplicated slashes for executables in those directories. See GitHub issue #191. Bonus fixes: - handle backslashes as well as slashes in concat_path_file() - convert backslashes to slashes in the output of 'type', 'command -v'
* | ash: skip NULL argv during forkshellRon Yorston2020-06-211-67/+44
| | | | | | | | | | | | | | | | Alter argv_size()/argv_copy() to omit argv from the forkshell block if it's NULL. Improve forkshell debug code to properly account for parts of funcblock which aren't being used.
* | ash: changes to ctrl-c handlingRon Yorston2020-06-201-57/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make ctrl-c handling more like Unix. Remove the hSIGINT event and the code in waitpid_child() to catch it. Add a call to raise_interrupt() in ctrl_handler(). Prior to these changes interrupts in a child shell weren't properly handled. In release FRP-3466-g53c09d0e1 interrupting a sleep in a child shell results in both shells competing for input: ~ $ sh ~ $ sleep 10 ^C^C ~ $ ~ $ pwd sh: w: not found ~ $ sh: pd: not found ~ $ With recent changes: ~ $ sh ~ $ sleep 10 ^C ~ $ echo $? 130 ~ $ exit ^C ~ $ echo $? 130 ~ $ The error return from the parent shell is due to the lack of job control. Upstream BusyBox ash and dash both do the same when job control is disabled.

* | ash: reduce forkshell block size for FS_SHELLEXECRon Yorston2020-06-201-25/+46
| | | | | | | | | | It isn't necessary to pass the alias table or line editing history to a forkshell shell that's handling FS_SHELLEXEC.
