Check if a plug-in instance can debug the file in module.

Returns
Returns true if this Process plug-in instance can debug the executable, false otherwise.

size_t ProcessElfCore::DoReadMemory ( lldb::addr_t  vm_addr,

)
overridevirtual

Actually do the reading of memory from a process.

Subclasses must override this function and can return fewer bytes than requested when memory requests are too large. This class will break up the memory requests and keep advancing the arguments along as needed.

Parameters
[in]vm_addrA virtual load address that indicates where to start reading memory from.
[in]sizeThe number of bytes to read.
[out]bufA byte buffer that is at least size bytes long that will receive the memory bytes.
[out]errorAn error that indicates the success or failure of this operation. If error indicates success (error.Success()), then the value returned can be trusted, otherwise zero will be returned.
Returns
The number of bytes that were actually read into buf. Zero is returned in the case of an error.

◆ GetDynamicLoader()

lldb_private::DynamicLoader * ProcessElfCore::GetDynamicLoader ( )
overridevirtual

Get the dynamic loader plug-in for this process.

The default action is to let the DynamicLoader plug-ins check the main executable and the DynamicLoader will select itself automatically. Subclasses can override this if inspecting the executable is not desired, or if Process subclasses can only use a specific DynamicLoader plug-in.

◆ GetImageInfoAddress()

lldb::addr_t ProcessElfCore::GetImageInfoAddress ( )
overridevirtual

Get the image information address for the current process.

Some runtimes have system functions that can help dynamic loaders locate the dynamic loader information needed to observe shared libraries being loaded or unloaded. This function is in the Process interface (as opposed to the DynamicLoader interface) to ensure that remote debugging can take advantage of this functionality.

Returns
The address of the dynamic loader information, or LLDB_INVALID_ADDRESS if this is not supported by this interface.

◆ parseLinuxNotes()

llvm::Error ProcessElfCore::parseLinuxNotes ( llvm::ArrayRef< lldb_private::CoreNote notes)
private

A description of a linux process usually contains the following NOTE entries:

  • NT_PRPSINFO - General process information like pid, uid, name, ...
  • NT_SIGINFO - Information about the signal that terminated the process
  • NT_AUXV - Process auxiliary vector
  • NT_FILE - Files mapped into memory

Additionally, for each thread in the process the core file will contain at least the NT_PRSTATUS note, containing the thread id and general purpose registers. It may include additional notes for other register sets (floating point and vector registers, ...). The tricky part here is that some of these notes have "CORE" in their owner fields, while other set it to "LINUX".

◆ parseNetBSDNotes()

llvm::Error ProcessElfCore::parseNetBSDNotes ( llvm::ArrayRef< lldb_private::CoreNote notes)
private

NetBSD specific Thread context from PT_NOTE segment.

NetBSD ELF core files use notes to provide information about the process's state. The note name is "NetBSD-CORE" for information that is global to the process, and "NetBSD-CORE@nn", where "nn" is the lwpid of the LWP that the information belongs to (such as register state).

NetBSD uses the following note identifiers:

 ELF_NOTE_NETBSD_CORE_PROCINFO (value 1)
        Note is a "netbsd_elfcore_procinfo" structure.
 ELF_NOTE_NETBSD_CORE_AUXV     (value 2; since NetBSD 8.0)
        Note is an array of AuxInfo structures.

NetBSD also uses ptrace(2) request numbers (the ones that exist in machine-dependent space) to identify register info notes. The info in such notes is in the same format that ptrace(2) would export that information.

◆ ReadMemory()

size_t ProcessElfCore::ReadMemory ( lldb::addr_t  vm_addr,
void *  buf,
size_t  size,
lldb_private::Status error 
)
overridevirtual

Read of memory from a process.

This function will read memory from the current process's address space and remove any traps that may have been inserted into the memory.

This function is not meant to be overridden by Process subclasses, the subclasses should implement Process::DoReadMemory (lldb::addr_t, size_t, void *).

Parameters
[in]vm_addrA virtual load address that indicates where to start reading memory from.
[out]bufA byte buffer that is at least size bytes long that will receive the memory bytes.
[in]sizeThe number of bytes to read.
[out]errorAn error that indicates the success or failure of this operation. If error indicates success (error.Success()), then the value returned can be trusted, otherwise zero will be returned.
Returns
The number of bytes that were actually read into buf. If the returned number is greater than zero, yet less than size, then this function will get called again with vm_addr, buf, and size updated appropriately. Zero is returned in the case of an error.

◆ ReadMemoryTags()

llvm::Expected< std::vector< lldb::addr_t > > ProcessElfCore::ReadMemoryTags ( lldb::addr_t  addr,
size_t  len 
)
overridevirtual

Read memory tags for the range addr to addr+len.

It is assumed that this range has already been granule aligned. (see MemoryTagManager::MakeTaggedRange)

This calls DoReadMemoryTags to do the target specific operations.

Parameters
[in]addrStart of memory range to read tags for.
[in]lenLength of memory range to read tags for (in bytes).
Returns
If this architecture or process does not support memory tagging, an error saying so. If it does, either the memory tags or an error describing a failure to read or unpack them.

◆ RefreshStateAfterStop()

void ProcessElfCore::RefreshStateAfterStop ( )
overridevirtual

Currently called as part of ShouldStop.

FIXME: Should really happen when the target stops before the event is taken from the queue...

This callback is called as the event is about to be queued up to allow Process plug-ins to execute some code prior to clients being notified that a process was stopped. Common operations include updating the thread list, invalidating any thread state (registers, stack, etc) prior to letting the notification go out.

◆ SupportsMemoryTagging()

bool ProcessElfCore::SupportsMemoryTagging ( )

◆ WarnBeforeDetach()

bool ProcessElfCore::WarnBeforeDetach ( ) const
inlineoverridevirtual

Before lldb detaches from a process, it warns the user that they are about to lose their debug session.

In some cases, this warning doesn't need to be emitted – for instance, with core file debugging where the user can reconstruct the "state" by simply re-running the debugger on the core file.

Returns
Returns true if the user should be warned about detaching from this process.

Definition at line 79 of file ProcessElfCore.h.

◆ WillResume()

lldb_private::Status ProcessElfCore::WillResume ( )
inlineoverridevirtual

Called before resuming to a process.

Allow Process plug-ins to execute some code before resuming a process.

Returns
Returns an error object.
