This issue is caused by udev, which +truncates /dev/md link until the first whitespace. + +This patch introduces prohibition of characters other than A-Za-z0-9.-_ +in the device name. Also, it prohibits using leading "-" in device name, +so name won't be confused with cli parameter. +Set of allowed characters is taken from POSIX 3.280 Portable Character +Set. Also, device name length now is limited to NAME_MAX. + +In some places, there are other requirements for string length (e.g. size +up to MD_NAME_MAX for device name). This routine is made to follow POSIX +and other, more strict limitations should be checked separately. +We are aware of the risk of regression in exceptional cases (as +escape_devname function is removed) that should be fixed by updating +the array name. + +The POSIX validation is added for: +- 'name' parameter in every mode. +- first devlist entry, for Build, Create, Assemble, Manage, Grow. +- config entries, both devname and "name=". + +Additionally, some manual cleanups are made. + +Signed-off-by: Mariusz Tkaczyk +Signed-off-by: Jes Sorensen +--- + Detail.c | 17 ++++-------- + config.c | 13 ++++++--- + lib.c | 58 ++++++++++++++++++++++++++++----------- + mdadm.8.in | 70 ++++++++++++++++++++--------------------------- + mdadm.conf.5.in | 4 --- + mdadm.h | 2 +- + super-intel.c | 47 ++++++++++++++++--------------- + tests/00confnames | 4 +-- + 8 files changed, 113 insertions(+), 102 deletions(-) + +diff --git a/Detail.c b/Detail.c +index 206d88e3..57ac336f 100644 +--- a/Detail.c ++++ b/Detail.c +@@ -254,11 +254,9 @@ int Detail(char *dev, struct context *c) + fname_from_uuid(st, info, nbuf, ':'); + printf("MD_UUID=%s\n", nbuf + 5); + mp = map_by_uuid(&map, info->uuid); +- if (mp && mp->path && strncmp(mp->path, DEV_MD_DIR, DEV_MD_DIR_LEN) == 0) { +- printf("MD_DEVNAME="); +- print_escape(mp->path + DEV_MD_DIR_LEN); +- putchar('\n'); +- } ++ ++ if (mp && mp->path && strncmp(mp->path, DEV_MD_DIR, DEV_MD_DIR_LEN) == 0) ++ printf("MD_DEVNAME=%s\n", mp->path + DEV_MD_DIR_LEN); + + if (st->ss->export_detail_super) + st->ss->export_detail_super(st); +@@ -271,12 +269,9 @@ int Detail(char *dev, struct context *c) + __fname_from_uuid(mp->uuid, 0, nbuf, ':'); + printf("MD_UUID=%s\n", nbuf+5); + } +- if (mp && mp->path && +- strncmp(mp->path, DEV_MD_DIR, DEV_MD_DIR_LEN) == 0) { +- printf("MD_DEVNAME="); +- print_escape(mp->path + DEV_MD_DIR_LEN); +- putchar('\n'); +- } ++ if (mp && mp->path && strncmp(mp->path, DEV_MD_DIR, DEV_MD_DIR_LEN) == 0) ++ printf("MD_DEVNAME=%s\n", mp->path + DEV_MD_DIR_LEN); ++ + map_free(map); + } + if (!c->no_devices && sra) { +diff --git a/config.c b/config.c +index a0424845..5f12a1f8 100644 +--- a/config.c ++++ b/config.c +@@ -199,9 +199,9 @@ inline void ident_init(struct mddev_ident *ident) + * /dev/md_d{number} (legacy) + * /dev/md_{name} + * /dev/md/{name} +- * {name} - anything that doesn't start from '/' or '<'. ++ * {name} + * +- * {name} must follow name's criteria. ++ * {name} must follow name's criteria and be POSIX compatible. + * If criteria passed, duplicate memory and set devname in @ident. + * + * Return: %MDADM_STATUS_SUCCESS or %MDADM_STATUS_ERROR. +@@ -241,8 +241,8 @@ mdadm_status_t _ident_set_devname(struct mddev_ident *ident, const char *devname + else + name = devname; + +- if (*name == '/' || *name == '<') { +- ident_log(prop_name, devname, "Cannot be started from \'/\' or \'<\'", cmdline); ++ if (is_name_posix_compatible(name) == false) { ++ ident_log(prop_name, name, "Not POSIX compatible", cmdline); + return MDADM_STATUS_ERROR; + } + +@@ -283,6 +283,11 @@ static mdadm_status_t _ident_set_name(struct mddev_ident *ident, const char *nam + return MDADM_STATUS_ERROR; + } + ++ if (is_name_posix_compatible(name) == false) { ++ ident_log(prop_name, name, "Not POSIX compatible", cmdline); ++ return MDADM_STATUS_ERROR; ++ } ++ + snprintf(ident->name, MD_NAME_MAX + 1, "%s", name); + return MDADM_STATUS_SUCCESS; + } +diff --git a/lib.c b/lib.c +index 03198e2d..7ab59988 100644 +--- a/lib.c ++++ b/lib.c +@@ -483,24 +483,50 @@ void print_quoted(char *str) + putchar(q); + } + +-void print_escape(char *str) ++/** ++ * is_alphanum() - Check if sign is letter or digit. ++ * @c: char to analyze. ++ * ++ * Similar to isalnum() but additional locales are excluded. ++ * ++ * Return: %true on success, %false otherwise. ++ */ ++bool is_alphanum(const char c) + { +- /* print str, but change space and tab to '_' +- * as is suitable for device names +- */ +- for (; *str; str++) { +- switch (*str) { +- case ' ': +- case '\t': +- putchar('_'); +- break; +- case '/': +- putchar('-'); +- break; +- default: +- putchar(*str); +- } ++ if (isupper(c) || islower(c) || isdigit(c) != 0) ++ return true; ++ return false; ++} ++ ++/** ++ * is_name_posix_compatible() - Check if name is POSIX compatible. ++ * @name: name to check. ++ * ++ * POSIX portable file name character set contains ASCII letters, ++ * digits, '_', '.', and '-'.
