It supports erasing of symbol data and ## it's members of any data type. In case of filtering of data pointed by ## void * pointer, user needs to provide size to filter out. ## ## Please refer to manpage makedumpfile.conf(5) for more details. ## ## ## - Module section ## ========================================================= ## Syntax: ## [ModuleName] ## ## Define the module section where the symbols specified in subsequent erase ## commands belong to. The section name is a kernel module name (including ## vmlinux). The unnamed section defaults to [vmlinux] section. ## ## NOTE: There should not be any whitespaces before or after the ModuleName. ## ## e.g. ## [vmlinux] # Symbols in erase command belongs to main kernel (vmlinux) ## erase modules ## erase cred_jar.name ## erase cred_jar.name size 10 ## erase cred_jar.array ## erase vmlist.addr nullify ## ## [z90crypt] # Symbols in erase command belongs to kernel module z90crypt ## erase ap_device_list ## ## # erase entire CPRBX structure ## erase static_cprbx ## ## ## - To erase kernel data referred through a kernel Symbol ## ========================================================= ## Syntax: ## erase <Symbol>[.member[...]] [size <SizeValue>[K|M]] ## erase <Symbol>[.member[...]] [size <SizeSymbol>] ## erase <Symbol>[.member[...]] [nullify]] ## ## where ## <Symbol> ## A variable name from the kernel or module, which is part of ## global symbols '/proc/kallsyms'. ## <SizeValue> ## Integer value that specifies size of data to be erased. The ## suffixes 'K' and 'M' can be used to specify kilobytes and ## megabytes respectively where, K means 1024 bytes and M means ## 1024 ^ 2 = 1048576 bytes. ## <SizeSymbol> ## A simple axpression of the form <Symbol>[.member[...]] that ## denotes a symbol which contains a positive integer value as a ## size of the data in bytes to be erased. ## ## Filter out the specified size of the data referred by symbol/member. ## If size option is not provided then the size of <Symbol> will be calculated ## according to it's data type. For 'char *' data type, string length will be ## determined with an upper limit of 1024. ## ## If specified <Symbol> is of type 'void *', then user needs to provide ## either 'size' or 'nullify' option. Otherwise erase command will not have ## any effect. ## ## The option 'nullify' will work only if filter symbol/member is a pointer and ## is used to set NULL value to the pointer type symbol/member. ## ## NOTE: Please note that by nullifying pointer values will affect the ## debug ability of created DUMPFILE. Use 'nullify' option only when size of ## data to be filter out is not known e.g. data pointed by 'void *'. ## ## e.g. ## [vmlinux] ## erase modules ## erase cred_jar.name ## erase cred_jar.name size 10 ## erase cred_jar.array ## erase vmlist.addr nullify ## ## ## - To filter kernel data referred through Array/list_head Symbol ## ================================================================= ## Syntax: ## for <id> in { <ArrayVar> | ## <StructVar> via <NextMember> | ## <ListHeadVar> within <StructName>:<ListHeadMember> } ## erase <id>[.MemberExpression] [size <SizeExpression>|nullify] ## [erase <id> ...] ## [...] ## endfor ## ## where ## <id> ## Arbitrary name used to temporarily point to elements of the ## list. Referred as iteration variable. ## <ArrayVar> ## A simple expression in the form of <Symbol>[.member[...]] that ## results into an array variable. ## <StructVar> ## A simple expression in the form of <Symbol>[.member[...]] that ## results into a variable that points to a structure. ## <NextMember> ## Member within <StructVar> that points to an object of same ## type that of <StructVar>. ## <ListHeadVar> ## A simple expression in the form of <Symbol>[.member[...]] that ## results into a variable of type struct list_head. ## <StructName> ## Name of the structure type that can be traversed using ## HEAD variable <ListHeadVar> and contains a member named ## <ListHeadMember>. ## <ListHeadMember> ## Name of a member in <StructName>, of type struct list_head. ## <MemberExpression> ## A simple expression in the form of [.member[...]] to specify a ## member or component of a member in <ArrayVar>, <StructVar> or ## <StructName>. ## <SizeExpression> ## One of the following: ## - An integer value. ## - <Symbol>[.member[...]] ## - <id>[.MemberExpresion] ## ## The <ArrayVar>, <StructVar> and <ListHeadVar> is also referred as LIST ## entry ## ## Filter out the specified size of the data accessible through LIST entries. ## e.g. ## [vmlinux] ## # Traversing <ListHeadVar> ## for m in modules.next within module:list ## erase m.holders_dir.name ## endfor ## # Traversing <ArrayVar> ## for lc in lowcore_ptr ## erase lc ## endfor ## # Traversing link-list ## for cj in cred_jar via slabp_cache ## erase cj.name ## endfor ## [z90crypt] ## for ap_dev in ap_device_list.next within ap_device:list ## erase ap_dev.reply.message size ap_dev.reply.length ## endfor ##
